Arrange the following in increasing order of stability, 
.
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
In 
, there is a triple bond while in 
, there is a double bond and the atoms of 
and 
are connected by a single bond. The bond energy will increase as the number of bonds between atoms increases. So, bond energy of 
and 
will be more than 
and 
. Between 
and 
has more bonding electrons 
than 
. Both 
and 
have similar bond order, but 
has more B.E. than 
. Thus, the order of stability in increasing order is 
.
