Question

Q.) Propanone forms an addition product with HCN. Give one reason

Answer 1

Heya mate here is your answer ☺️☺️↙️↙️↙️

Ans =
Propanone reacts with HCN to form addition product.
CH3COCH3 + HCN →CH3C(OH) (CN)CH3 

A HCN molecule gets added to carbonyl (C=O) group of propanone and hence addition reaction takes place.

Hope this helps you mate ⭐⭐✌️✌️☺️☺️✅✅✅

Answer 2

$\huge \mathfrak {Answer:-}$

Propanone reacts with HCN to form $\bold{addition\: product.}$

$CH_{3}COCH_{3}$ + $HCN$ => $CH_{3}C(OH)$ $(CN)CH_{3}$

Since,

A HCN molecule gets $\bold{added\:to\:carbonyl}$ $(C=O)$ group of propanone and hence $\bold{addition\:reaction}$ takes place.
