(3) linear

Answer 1

If C bonds all single bonds than the hybridization is sp3 and if it form one double bond than hybridization is sp2 and if C form one triple bond or two double bonds than hybridization is sp The formula to calculate hybridization is: nF 1/2 [group no. central atom +no. of monovalent atoms attached to central metal atom (except oxygen) + magnitude of negative charge - magnitude of positive charge] for C-1 1 1/2 [4+4 +0-0] NE 1/2 [8) For O atom The hybridization is sp3 and the electron geometry is tetrahedral. For carbon -2 nE 1/2 [group no. central atom +no. of monovalent atoms attached to central metal atom (except oxygen) + magnitude of negative charge - magnitude of positive charge] For double bonded C: = 1/2 [6 +2) F 1/2 [group no. central atom +no. of monovalent atoms attached to central metal atom (except oxygen) + magnitude of negative charge - magnitude of positive charge] -4 Means sp3 hybridized. n= 1/2 [4 +2) =3 The hybridization is sp3 and the electron geometry is tetrahedral but due to presence of two lone pair it is bent or V shape. Means sp2 hybridized. The hybridization is sp2 and the electron geometry is trigonal planner
