Question

molecule of highest % s-character among the following
C2H2
C2H4
C3H6
C3H8

Answer 1

Answer:

c3H8 has highest % s-character among the following

Answer 2

$C_2H_2$ has the highest % of s' characters.

• $C_2H_2$ is an alkyne. Here carbon atom is sp hybridised and contains 50% s' character.
• $C_2H_4$ is an alkene. Here carbon atom is $sp^2$ hybridised and contains 33.33% s' character.
• $C_3H_6$ is an alkene. Here one carbon atom is $sp^2$ hybridised and one is $sp^3$ hybridised so, contains 33.33% and 25'% s' character.
• $C_3H_8$ is an alkane. Here carbon atom is $sp^3$ hybridised and contains 25% s' character.
• So, $C_2H_2$ has the highest % of s' characters.
