Number of p pi- p pi , double bond in given compound CN-CN = CH-CN is ____.

Match List I with List II and select the correct answer using the codes given below the lists : {:("List "I,,"List "II),(a.(SiH_(3))_(3)N,,i. "3 centre -2-electron bond"),(b.BF_(2),,ii. sp^(3)-"hybridization"),(c. SiO_(2),,iii.p pi-p pi " bond"),(d.B_(2)H_(6),,iv.p pi-p pi " bond"):} Code :

Which readily form p pi-p pi multiple bonds with itself and with C and O among VA group elements ?

Assertion : Both rhombic and monoclinic sulphur exist as S_(8) but oxygen exists as O_(2) . Reason : Oxygen forms p pi- p pi multiple bond due to small size and small length but p pi - p pi bonding is not possible in sulphur.
