Dipole moment of cis-2, 3-dichloro-2 butne is ….. Than the dipole moment of cis1, 2-dichloroethene.

Expalin the following (a) The central C-C bond in Buta 1,3 diene is shorter than that of n-butane (b) Why the dipole moment of cis-1,2 dichloroethene is greater than that of trans -1,2 -dichloroethene (c ) CIF_(2)^(Θ) is linear, but CIF_(2)^(o+) is bent (d )Two different bond lengths are observed in PF_(5) but only one bond lenght is observed in SF_(6) .

S-I: The boiling point of cis-1,2-dichloroethene is higher than corresponding trans-isomer. S-II: The dipole moment of cis-1,2-dichloroethene is higher than trans isomer.
