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.
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.

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.
