Did edit window open??

Guys what all is visible to you in freshers portal could someone update below

Hows the hostel wifi

When does the hostel dees and allocation prcess start for freshers and when is the orientation and date of start of classes further more if we want to with draw we will also get the hostel fees refunded right

Can we prepay sbi scholar loans

Is ECE at IIIT DHARWAD worth it over vit vellore cse

Guys I forgot to upload my class 12 marksheet during preference form filling please tell if I can upload in the future????

Seniors do we pay for hostel at the vit vellore campus or in the freshers portal a month before

Could any seniors give me a timeline and process for internships of dual degree holders. I my understanding they dont have ps1 but have s1 and ps2 also what do these signify like what do these particular intenships entail like no pay etc???

So how stressfull is it and what percentage of stu get mnc or cse allotted. Also how many extra courses per sem for a dual degree student.

Please advise me on this seniors

Could you please clarify the dual-degree allotment process for MSc students? My understanding is that students can opt for a dual degree at the end of their second semester, with course availability being determined by their first-year CGPA. Is this correct?

Also Does anybody have branch cutoffs for BE allotment of last year in BITS Hyd Campus

Guys 100 percent some kind of cheating happened this year because the data seems so anomalous and impossible

Guys feel like mathongo ke ranges ke waja se 5 to 9 makrs increase hue hai from my friend it went from 170 to 179 in math ongo so after officail key sabke niche jayenge also i think the data has almost reached peak saturation

Guys stop fearmongering assuming that in reality 1.5 times more people are sitting in this rank range at 90 it still goes to 16614 also the data is skewed in the midrange as mostly students who are mid will check while toppers and people getting very less marks will not be checking take a chill 💊

ALSO WE ARE HAVING 8864 STUDENTS ABOVE 100 SO EVEN IFF WE DOUBLE IT LOOKS LIKE 2025 but obviously it will not be double ad midrange data is skewed so take it as 1.5 to 1.7 about the nos of people above you

Perfect Stoichiometric Equations for Calculations

1. Formic Acid ($HCOOH$)

Formic acid is the only carboxylic acid to give these tests because the Carbon-Hydrogen bond attached to the carboxyl group acts like an aldehyde.

• Tollens': $HCOOH + 2[Ag(NH_3)_2]^(+) + 2OH^(-) \rightarrow CO_2 + 2Ag(s) + 4NH_3 + 2H_2O$
  • Ratio: $1 \text{ mol } HCOOH \rightarrow 2 \text{ mol } Ag$
• Fehling's: $HCOOH + 2Cu^({2+}) + 4OH^(-) \rightarrow CO_2 + Cu_2O(s) + 3H_2O$
  • Ratio: $1 \text{ mol } HCOOH \rightarrow 1 \text{ mol } Cu_2O$

2. $\alpha$-Hydroxy Ketones ($R-CH(OH)-CO-R$)

These react because they undergo Lobry de Bruyn–van Alberda van Ekenstein transformation in the basic medium of the reagents to form aldehydes.

• Equation: Treated effectively the same as aldehydes in calculations.
  • Ratio: $1 \text{ mol ketone} \rightarrow 2 \text{ mol } Ag$

3. Hydrazines ($NH_2NH_2$ or $R-NHNH_2$)

Hydrazines are very powerful reducing agents. Phenylhydrazine is often used in carbohydrate chemistry (Osazone formation) and will reduce Tollens' reagent to silver.

• Tollens' (Hydrazine): $NH_2NH_2 + 4[Ag(NH_3)_2]^(+) + 4OH^(-) \rightarrow N_2 + 4Ag(s) + 8NH_3 + 4H_2O$
  • Ratio: 1 : 4 (Crucial for stoichiometry!)
• Tollens' (Phenylhydrazine): $C_6H_5NHNH_2 + 2[Ag(NH_3)_2]^(+) + OH^(-) \rightarrow C_6H_6 + N_2 + 2Ag(s) + 4NH_3 + H_2O$
  • Ratio: 1 : 2

4. Hydroxylamines ($R-NHOH$)

• Tollens': $R-NHOH + 2[Ag(NH_3)_2]^(+) + OH^(-) \rightarrow R-NO + 2Ag(s) + 4NH_3 + H_2O$
  • Ratio: $1 \text{ mol Hydroxylamine} \rightarrow 2 \text{ mol } Ag$

5. Polyhydroxy Phenols (Hydroquinone)

Used in photography as "developers" precisely because they reduce silver ions to metallic silver.

• Equation: $C_6H_4(OH)_2 + 2[Ag(NH_3)_2]^(+) \rightarrow C_6H_4O_2 (\text{Quinone}) + 2Ag(s) + 2NH_4^(+) + 2NH_3$
  • Ratio: $1 \text{ mol Phenol} \rightarrow 2 \text{ mol } Ag$

6. Ascorbic Acid (Vitamin C / Reductones)

The enediol structure is highly sensitive to oxidation.

• Equation: $C_6H_8O_6 + 2[Ag(NH_3)_2]^(+) \rightarrow C_6H_6O_6 (\text{Dehydroascorbic acid}) + 2Ag(s) + 2NH_4^(+) + 2NH_3$
  • Ratio: $1 \text{ mol Vitamin C} \rightarrow 2 \text{ mol } Ag$

Summary Checklist for Stoichiometric Analysis

If you are given a mass of "Silver Mirror" or "Red Precipitate" and asked to identify or quantify the organic compound:

1. Ag : Organic = 2 : 1 $\rightarrow$ Standard Aldehyde, Aromatic Aldehyde, Formic Acid, $\alpha$-Hydroxy Ketone, or Hydroxylamine.
2. Ag : Organic = 4 : 1 $\rightarrow$ Hydrazine ($N_2H_4$).
3. $Cu_2O$ : Organic = 1 : 1 $\rightarrow$ Aliphatic Aldehyde or Formic Acid.
4. $Cu_2O$ : Organic = 2 : 1 $\rightarrow$ Formaldehyde (if oxidized all the way to $CO_3^({2-}$) in excess reagent).

Note on $\alpha,\beta$-unsaturated ketones: If you encounter a problem where an unsaturated ketone gives a positive test, look closely at the structure. If it is an $\alpha,\beta$-unsaturated aldehyde (like Acrolein), it is (+). If it is a ketone with an $-\text{OH}$ group on the adjacent carbon, it is (+). Otherwise, simple ketones are consistently negative.
