Chemical Bonding And Molecular Structure Question 122

Question: The electronic structure of four elements A, B, C, D are (i) $ 1s^{2} $ (ii) $ 1s^{2},2s^{2},2p^{2} $ (iii) $ 1s^{2},2s^{2},2p^{5} $ (iv) $ 1s^{2},2s^{2},2p^{6} $ The tendency to form electrovalent bond is largest in [MNR 1987, 95]

Options:

A) A

B) B

C) C

D) D

Show Answer

Answer:

Correct Answer: C

Solution:

Element C has electronic structure $ 1s^{2},2s^{2}2p^{5} $ , it requires only one electron to complete its octet and it will form anion so it will form electrovalent bond.
