Consider following statements.
(a) molecule does not exist.
(b) Energy of molecular orbital is always higher than that of and molecular orbital.
(c) The formation of molecular orbitals may be described by linear combination of atomic orbitals.
The correct statement(s) is/are
(a) molecule does not exist.
(b) Energy of molecular orbital is always higher than that of and molecular orbital.
(c) The formation of molecular orbitals may be described by linear combination of atomic orbitals.
The correct statement(s) is/are
View answer and explanation
Correct option: B
(a) and (c) only
Option B ((a) and (c) only) is correct because He2 molecule does not exist due to zero bond order, and molecular orbitals are formed by linear combination of atomic orbitals (LCAO).
