Question

In group 13, electronegativity first decreases from B to Al and then increases marginally down the group. This is because of (A) non-metallic nature of B (B) discrepancies in atomic size of elements (C) ability of B and Al to form pπ - pπ multiple bonds (D) irregular trend in electronegativity throughout the periodic table

There is a large size difference between B and Al.

Q. In group $13$ , electronegativity first decreases from $B$ to $A l$ and then increases marginally down the group. This is because of

non-metallic nature of $B$

discrepancies in atomic size of elements

ability of $B$ and $A l$ to form $p π - p π$ multiple bonds

irregular trend in electronegativity throughout the periodic table

There is a large size difference between $B$ and $A l$ .
