(i) `RC-=overset(-)overset(..)C` , (ii)
(iii) `R_(2)C=overset(-)overset(..)CH` , (iv) `R_(3)C-overset(-)overset(..)CH_(2)`
is in the order

A

(iv) gt (ii) gt (iii) gt (i)

B

(i) gt (iii) gt (ii) gt (iv)

Text Solution

Verified by Experts

The correct Answer is:
C
More is the electronegativity of hybrid atom, more will be its tendency to retain the `(-)ve` charge.

The electronegativity of hybrid orbitals, depends on their 's' character. It follows given order,
`overset(spgt sp^(2)gtsp^(3))underset("electronegativity mcreases")larr`
