Q. The incorrect order of bond dissociation energy will be :
A. H – H > Cl – Cl > Br – Br
B. Si – Si > P – P > Cl – Cl (Correct Answer)
C. C – C > N – N > O – O

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Explanation which I received: as we proceed from left to right in the period, we know that electronegativity increases and atomic size decreases so bond becomes stronger hence order of Bond Dissociation Energy will be Si-Si < P-P < Cl-Cl
