1butan-2-one and butan-3-one are not two different compound .
The smallest ketone and its next homologue are reacted with NH2OH to forn oxime.
(a) two different oximes are formed.
(b)three diff oximes are formed .
(c)two oximes are optically active.
(d) all oximes are optically active.
plzzz give the reason along with the answer.

39The smallest ketone is, I think, acetone? And it's next homologue is CH3-CO-CH2-CH3.
I think it's pretty obvious that two different oximes are formed. About optical activity I'm not so sure.
1ans is b) becauz 1 form from acetone while next homologue is butan-2-one or butane-3-one
there4 3 oxime r formed!!!!!
23there will b 3
when acetone is reacted we get 1 oxime
when next homologue is reacted we get an oxime , which can either be E form or Z form
( i.e like cis /trans ) bcz of the bulky lone pair on N .
1As @mohit senger said in his answer, acetone forms one oxime and butanone forms two oximes, one E and the other, Z. They are not optically active despite what is written in arihant's 39 years jee chemistry question bank.
