1.	Aqueoussolutionsof twocompoundsM- O- Hand M'- O - Hhavebeenpreparedin twoseparatebeakers. It theelectronegativity ofM= 3.5M= 1.72 ,O = 3.0 andand H=2.1then thesolutions respectively are
Answer» acidic , acidic acidicbasic basic , basic basicacidic SOLUTION :As theelectronegativityof metalincreasethe electrondensityin the O - Hbonddecreases . Inorderwords O - Hbondbecomesweakand readilyionizes toliberate`H^(+)` ThusM-O- Hbehave as an acid. CONVERSELY as theelecronegativityof the metaldecreasesM- Obondbecomesweakandreadilyionizesto LIBERATE `OH^(-)` Thus `M- O- H` behavesas a base. combiningboththe trendsoption (b) is correct.
