Question

The correct increasing order of non-metallic character is:

• A. $B<C<Si<N<F$
• B. $Si<C<B<N<F$
• C. $Si<B<C<N<F$
• D. $F<N<C<Si<B$

Answer 1

The correct option is C $Si<B<C<N<F$

The non-metallic character decreases down the group .
Hence, the increasing order of non-metallic character of $C$ and $Si$ is $Si<C$.
Non-metallic character increases in a period as we move from left to right.
So, the increasing order of non-metallic character $B<C<N<F$
Silicon is in ${14}^{th}$ group and is also a metalloid so has less non metallic character than B
Overall order of non-metallic character is: $Si<B<C<N<F$
