The structure of diborane (B2H6) contains
four 2C-2e- bonds and four 3C-2e- bonds
two 2C-2e- bonds and two 3C-3e- bonds
two 2C-2e- bonds and four 3C-2e- bonds
four 2C-2e- bonds and two 3C-2e- bonds
In silica (SiO2), each silicon atom is bonded to
two oxygen atoms
four oxygen atoms
one silicon and two oxygen atoms
one silicon and four oxygen atoms
C-C bond length is maximum in
diamond
graphite
naphthalene
fullerone
A.
diamond
In diamond sp3 hybridisation is present while in graphite, napthalene and fullerene sp2 hybridisation is present therefore, the C-C bond length is maximum in diamond.
