Last Answer : Double bond: Benzene, pentene Triple bond: Ethyne, Butyne
Description : Why is CO2 a linear molecule while SO2 a non-linear molecule?
Last Answer : Ans. In SO2 molecule there are two bond pairs and one lone pair of electron .Due to repulsion by lone pair its bond angle decreases from 120° to 119.5° hence it is not linear whereas in CO2 molecule there is no lone pair of electron due to which it has linear geometry.

Description : Use the information and data given below to answer the questions Stronger intermolecular forces result in higher boiling point Strength of London forces increases with the number of electrons in the molecule ... here? (c) Why is the boiling point of HF highest while that of HCl lowest?
Last Answer : Ans :( a) In the molecules HCl, HBr and HI, dipole-dipole interaction and London forces are present. (b) Dipole moment of HCl > HBr > HI but boiling point of HCl < HBr
Description : Explain the formation of H2 molecule on the basis of valence bond theory.
Last Answer : Ans. When two H atoms come closer the following forces operate between them: a. Attractive : i.nucleus of atom and its electron ii.nucleus of one atom and electron of other. b.repulsive ... and the system acquires minimum energy .At this stage two hydrogen atoms are said to be bonded together.
Description : Explain why the water molecule has a bent shape and a bond angle less than 109.5° The electron repulsion between the two lone pairs of electrons on the oxygen of water causes the O–H bonds to squeeze close together
Last Answer : The electron repulsion between the two lone pairs of electrons on the oxygen of water causes the O–H bonds to squeeze close together
