दिलेल्या संयुजा कक्षेतील इलेक्ट्रॉनच्या जोड्यांमधील – उदा. विमुक्त जोडी – विमुक्त जोडी (वि.जो. – वि.जो.); बंधित जोडी – बंधित जोडी (बं.जो. – बं.जो.) व विमुक्त जोडी – बंधित जोडी (वि.जो. – बं.जो.) विद्युतस्थितिक प्रतिकर्षंन _______ असे कमी होत जाते. The electrostatic repulsion between electron pairs such as lone pair – lone pair (l.p. – l.p.), bond pair – bond pair (b.p. – b.p.) and lone pair – bond pair (l.p. – b.p.) in a given valence shell decreases in the order of _______
According to VSEPR theory, electrostatic repulsion between electron pairs follows the order: lone pair - lone pair (lp-lp) > lone pair - bond pair (lp-bp) > bond pair - bond pair (bp-bp).
खालील दिलेल्या विधानापैकी कोणती विधाने बरोबर आहेत ? Which of the following statements are correct?
(a)HF आणि H₂O ही ध्रुवीय संयुगे आहेत. / HF and H₂O are polar molecules.
(b)CH₄ आणि CO₂ ही ध्रुवीय संयुगे नाहीत. / CH₄ and CO₂ are non-polar molecules.
(c)CO₂ आणि SO₂ ही ध्रुवीय संयुगे नाहीत. / CO₂ and SO₂ are non-polar molecules.
HF and H2O are polar molecules due to significant electronegativity difference and bent/asymmetrical geometry. CH4 and CO2 are non-polar due to symmetrical geometry cancelling dipoles.
