Chemical BondingHybridization and Bond Angle26Choose the best answerThe correct increasing order of ideal bond angles for these hybridizations is:Asp < sp² < sp³Bsp² < sp³ < spCsp³ < sp² < spDsp = sp² = sp³ Like 0 Discuss 0Share
Chemical BondingBond Length, Bond Order and Hybridization27Choose the best answerThe C–C bond lengths in ethane, ethene and ethyne are approximately 154 pm, 133 pm and 120 pm, respectively. This decrease in bond length is mainly due to:AIncreasing s-character from sp³ to sp hybridizationBIncreasing bond order from single to triple bondCBoth A and BDIncreasing atomic size of carbon Like 0 Discuss 0Share
