4. CCl4
Which is not true according to VBT-
1. A covalent bond is formed by the overlapping of orbitals with unpaired electrons of opposite spins.
2. A covalent bond is formed by the overlapping of orbitals with unpaired electrons of same spin.
3. The greater the extent of overlapping the stronger is the bond.
4. Overlapping takes place only in the direction of maximum electron density of the orbital.
