Question

Question 4 Determine if each of the statements is True or False about bonding molecular orbitals and antibonding molecular orbitals. 1) Every electron that enters a bonding molecular orbital has lower energy and stabilizes the molecule. Select 2) Bonding molecular orbitals are formed by the overlap of two out-of-phase atomic orbitals. [Select] 3) An antibonding molecular orbital has a lower electron density in the internuclear region than that of the atomic orbitals. [ Select] 4) Two atomic orbitals are combined to form two molecular orbitals. Select] Select False True Previous

Answer 1

(1) The bonding orbital have lower energy as compared to the anti-bonding orbital, le bonding orbital represents stability. If an election is placed in bonding orbital, it stablises the • Molecule. Therefore statement is true. 2). True . Let's take a general example :- 878 — (banding me) ( Anti-bonding I Mo) Thus Bonding the overlap of molecular orbitals (BMO) are formed by 2 out of phase atomic orbitals.

3) True) 4 the election present in bonding orbital then Detablied because it is in between the nuclei. Conversely, placing electrons into the anti-bonding I will decrease the stability of Molecule. it's two orbitals. OR we can say has lower that election anti-bonding density. Molecular orbital No. of Molecular orbitals. - formed. According to MOT - . No. of atomic orbitals combined Therefore, the statement [Ques-1) (SP) f — 1be — F is True # 70 Hp (303)
