Question Detail

CHM 102 P block elements Objective Question

Question

What is the maximum coordination number for the first row element in each P-block group, and why?
Options
A 6, because it has access to d-orbitals.
B 4, because it cannot expand its octet.
Correct Answer
C 8, due to the presence of multiple valence shells.
D 2, as it prefers to form only two bonds.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 6 states, 'The first element in each group cannot expand its octet hence the maximum coordination number for the first row element is 4.'

Hint

Think about the available orbitals for bonding in the second period elements.
