Compare rate of hydrogrnation in given figure

#1

#2

The more stable the particular alkene is ,the more easier to hydrogenate it.

Trans is most stable(least steric hindrance )
Followed by cis and then two groups on same carbon.
Rate is directly proportional to stability of alkene.

#3

Are you sure? As more stability implies less reactivity and our had also told us the same

Sorry pls ignore this post it’s indirectly proportional to stability .
So the answer is exactly reversed.

#5

How to compare stability of cis and 2 group on the same carbon?

#6

Compare which has less steric hindrance.
CIS has less steric hindrance compared to two groups in same carbon.

#7

Can anyone explain clearly how to compare rate of reaction between these 3?

#8

Order of Rate of reaction will be B>A>C.

#9

Reason?

#10

Rate of reaction is inversely proportional to the stability of compound.
Unstable compound is more reactive because compound try to attend stability.

#11

My main question is on which basis to compare stability?

#12

See there is lots of reasons on which you can compare stability of compound.
In the given question one of the main reason is steric hindrance. Two big group repulsion.

#13

stability leads to faster reaction this is the reason and stability is disturbed by repulsion between large groups
as the distance between two groups increases decreases repulsion giving more stability

#14

Trans is most stable(least steric hindrance )no.3

then comes no. 1

and then two groups on same carbon.no.2
3,1,2
Rate is directly proportional to stability of alkene
