Question

Give the correct order of bond lengths x, y and z in the above question​

Answer 1

Answer:

3) x>y>z

Explanation:

In x,

H is attached to a sp3 hybridised Carbon

In y,

H is attached to a sp2 hybridised Carbon

In z,

H is attached to a sp hybridised Carbon

Bond length increases with increasing p character or decreasing s character,

so, it follows the order

sp3>sp2>sp

Answer 2

The correct order is x>y>z.

• The x bond is attached to a $sp^3$ hybridised carbon atom.
• The bond y is attached to a $sp^2$ hybridised carbon atom.
• The bond z is attached to an sp hybridised carbon atom.
• As the 's' character increases the bond will draw the electron density more and the bond length decreases.
• Thus, the correct order bond length is x>y>z.
