The abnormality of HF is due to the presence of hydrogen bonding. They are covalent substances soluble in polar solvents. The bond strength of HX decreases down the group as the bonds become less polar. This property governs the reactivity of the halides.
Aldehydes and ketones react with a source of the hydride (H -) ion because the H-ion is a Lewis base, or nucleophile, that attacks the d + end of the C=O bond. When this happens, the two valence electrons on the H-ion form a covalent bond to the carbon atom.Since carbon is tetravalent, one pair of electrons in the C=O bond is displaced onto the oxygen to form an intermediate with a negative charge on the oxygen atom.hen this happens, the two valence electrons on the H-ion form a covalent bond to the carbon atom.
