(3 points) What is the bond order of NO? b. c. d. 2 1%

Answer 1

Answer :

9. (D) option is correct, it's bond order is zero.

Because there are two bonding electron present in molecular orbital diagram of He2 and 2 antibonding electron.therefore the bond order = 2-2/2 = 0/2 = 0.

10. (C), C-F option is correct, as we know that florine is most electronegative element in the periodic table therefore, it will have highest polar bond with Carbon.

11. (D) , 1 sigma and 1 π bond is correct. Because, there will be C=C and in which one bond is sigma while the other one is π bond.

12.(a) ,sp hybridization is correct option., Because, at C triple bond C , there is one sigma bond at terminal position while one sigma bond is in triple bond( which consists of 1 sigma and 2 π bond) , thus hybridization will be sp.

{ We are give only 4 answers in case of multiple type questions as per HomeworkLib guidelines, but still I am trying two more}

14. (D) sp3 for all, option is correct, there is 4 sigma bond will have sp3 hybridization.

15.(a) option is correct, 2*1/2.
