Q3 the rate limiting step is the step no 1 in which the formation new bond between terminal carbon and hydrogen (hydrazone anion)
Wolf kishner is the reduction of aldehyde and ketones to form alkanes
Q2: steps involved in reaction mechanism are
1 formation of hydrazone
2 deprotonation of nitrogen
3 protonation of carbon
4 deprotonation of nitrogen
5 protonation of carbon
Q3: rate determining step is the bond formation of terminal carbon with hydrogen
Ans no 1: The Wolff-kishner reduction is an organic reaction which used to convert an aldehyde or ketone to an alkane using hydrazone , hydrazine .
Ans no 2 : first step formation of hydrazone . 2nd step deprotonation of nitrogen . 3rd step protonation of the carbon . 4th step is again deprotonation of nitrogen . 5th step is protonation of carbon.
Ans no 3 : the rate limiting step is the lowest step of reaction . this reaction is the bond formation of the terminal carbon with hydrogen taking place basically the carbon-hydrogen bond formation is helped by mildly electron withdrawing substituents . highly electron withdrawing substituents decrease the negative charge of the terminal nitrogen , making it difficult to break the N-H bond .
Ans 1 : wolf kishner is the reduction of aldehydes and ketones to form alkanes Ans 2: first step : formation of hydrazone ,2 : deprotonation of nitrogen,3: protonation of carbon ,4: deprotonation of nitrogen ,5: protonation of carbon Ans 3: rate determining step of this reaction is the bond formation of terminal carbon with hydrogen .
