Question

6. Explain: Be has higher Di Hy than B​

Answer 1

Since 2s-electrons are more strongly attracted by the nucleus than 2p-electrons, therefore, lesser amount of energy is required to knock out a 2p-electron than a 2s-electron. Consequently, ∆iH of Be is higher than that ∆iH of B

Answer 2

Answer:

Since 2s-electrons are more strongly attracted by the nucleus than 2p-electrons, therefore, lesser amount of energy is required to knock out a 2p-electron than a 2s-electron.

Consequently, ∆iH of Be is higher than that ∆iH of B. ionisation enthalpy of F is higher than that of O.
