PLEASE HELP ME WITH THESE TWO QUESTIONSAnswers
The van der Waals forces, are distance dependent interactions between atoms. Unlike hydrogen or covalent bonds, these attractions are not a result of any chemical electronic bond and so this force is more susceptible to being perturbed C-O is polar bond due to difference in electronegativity. so the molecule can have dipole -dipole interaction as well as intermolecular hydrogen bonding Therefore correct statment is (D) the molecule has van der Waals forces, dipole -dipole interactions and intermolecular hydrogen bonding Formula ka Conjugate base Acid Stronger base CH3CH3 CH3CH2 Ethane CH2-CH NH2 HCzC Ethene CH2-CH2 Ammonia NH3 38 25 Stronger acid Acetylene HCECH Hence the correct order is: C) HCECHNH3 CH2-CH2CH CH Rule for acidity is more the pka value weaker the acid
