Solution

The correct option is A Electrons are simultaneously attracted by more than one nucleus.
The best description of a covalent bond is " Electrons are simultaneously attracted by more than one nucleus."
A covalent bond is formed when an orbital containing single electron of an atom overlaps with
an orbital containing single electron of another atom . Thus covalent bond involves sharing of electrons between two atoms.

Q. Assertion: The weakest of the bonds between molecules are coordinate covalent bonds.
Reason: Coordinate covalent bonds represent the weak attractive force of the electrons of one molecule for the positively charged nucleus of another.

The atoms or ions with available low-energy orbitals can attract loosely bonded pair of electrons from other molecules. A higher amount of positive charge on the side atom or ion makes its orbitals even more attractive for the loosely bonded electron pairs. The molecules with loosely bonded pairs also have different polarizabilities. The higher size of surrounding molecules and lower size of atom offering low energy orbitals increases crowding and diminishes the tendency of bonding.

Q. According to VBT any covalent bond will be formed by overlapping of valence atomic orbitals of bonded atoms provided atomic orbitals must be half–filled and electrons be in opposite spin.
According to type of overlapping covalent bonds can be classified as: (a)

σ

bond (b)

π

bond (c)

δ

bond.
The combination of orbital that cannot produce non–bonding molecular orbital is:
(internuclear axis is z–axis)

According to orbital overlap concept, the formation of a covalent bond between two atoms results by pairing of electrons present in the valence shell having opposite spins.
