Question 1 (1 point)Question 3 (1 point) Select the THREE true statements:Put these compounds in order of INCREASING heat of hydrogenation. Thecompound with the lowest heat of hydrogenation will be marked '1' Note that thenumber of double bonds is not the same in each compound.ONScheme AScheme BBQuestion 3 options:Scheme A shows two resonance structures, which means that the true structure is an average ofCthe two structures drawn.BScheme B shows two resonance structures, which means that the true structure is an average ofOthe two structures drawn.In the part of the diagram with resonance structures, the bond length is shorter than a doubleAbond, but longer than a single bond and has 1.5 bond orderIn the part of the diagram with resonance structures, the bond length is longer than a doubleQuestion 2 (1 point)bond, but shorter than a single bond and has 1.5 bond orderPut these structures in order of INCREASING heat of hydrogenation. The compoundwith the smallest value (lowest magnitude) for its heat of hydrogenation should beElectrons are delocalized in the scheme with resonance structuresgiven a value of '1'Electrons are localized in the scheme with resonance structuresQuestion 4 (1 point)|Select the TWO correct statementsH.H.O :ABCDHStructure AStructure BDOQuestion 4 options:Structure A is more stable because it has more octetsStructure A is more stable because it puts the positive charge on the better atomStructure B is more stable because it puts the positive charge on the better atomThe bond between C and N of this compound is shorter than a typical C-N single bondThe bond between C and N of this compound is shorter than a typical C=N double bond
