Question

Propane nitrile is obtained by the reaction of following 1. Ch3br+ kcn 2. C2h5br + kcn
3. Ch3br + agcn
4. C2h5br+ agcn

Answer 1

Please mark me brainliest and follow me

1. CH₃Br + KCN = CH₃CN + KBr

The products formed are ethane nitrile and potassium bromide

2. C₂H₅Br + KCN = C₂H₅CN + KBr

The products formed are propane nitrile, since there are three carbons and potassium bromide

3. CH₃Br + AgCN = CH₃NC + AgBr

Since the cyanide ion in AgCN is more covalent in nature and nitrogen donates its electron pair forming isocyanide as the main product

4. Same is in the case for C₂H₅Br + AgCN = C₂H₅NC

product formed is ethane isonitrile

So, the answer is option 2.
