Statement-I:
Statement-II: 2-butene is more stable than -2butene as it is having more `alpha-H`.

The effect that makes 2,3-dimethyl-2-butene more stable than 2-butene is :

The effect that makes 2, 3–dimethyl-2-butene more stable than 2-butene is :-

Cis - 2 - butene and trans - 2 - butene are

This question has statement I and Statement II . Of the four choices given after the statements, choose the one that best describes the two Statements. Statement-I: 2-Bromobutane on reaction with sodium ethoxide in ethanol gives 2-butene as a major product. Statement-II:2-Butene is more stable than-1-butene.

a. Cis- 2 -butene rarr trans- 2 -butane, DeltaH_(1) b. Cis- 2 -butane rarr1 -butene, DeltaH_(2) c. Trans- 2 -butene is more stable than C is- 2 -butene d. Ethalpy of combustion of 1 -butene, DeltaH =- 649.8 kcal//mol e. 9DeltaH_(1) +5DeltaH_(2) = 0 f. Enthalpy of combustion of trans -2 -butene, DeltaH =- 647.1 kcal mol^(-1) . Calculate DeltaH_(1) and DeltaH_(2) ?

Statement-I: Carbon-carbon double bond length in 2-butene is more than that of 1-butene. Statement-II: Hyperconjugation increases the bond length of carbon-carbon double bond.

This question has Statement I and Statement II, Of the four choices given after the Statement, choose the one that best describes the two Statements (1) Statement - I is true, Statement - II is true, Statement - II is a correct explanation of Statement - I (2) Statement - I is true - II is true, Statement - II is not a correct explanation of Statement - I (3) Statement - I is true, Statement - II is false Statement - I is false Statement - II is true Statement - I : The H-bonding of NH_3 and H_2O is represented as : Statement - II : H_2O is more acidic than NH_3 and thus, H_2O is a proton donor
