Can someone draw the entire mechanism with arrows for this reaction? I am mainly confused regarding two things:  1) The free radical (Br2/hv) addition of the bromine to cyclohex-1,4-diene 2) The addition of the epoxide and the deprotonated cyclohex-2,4-diol

When an unsymmetrical Alkenes such as propane is treated with N-bromosuccinimide in aqueous dimethyl sulfoxide, the major product has the bromine atom bonded to the less highly substituted carbon atom. Is this Markovnikov or non-Markovnikov orientation? Show its complete reaction mechanism.

Consider the attached SN2 reaction. Question: What happens to the reaction rate in each of the following instances? [1] The leaving group is changed from Br− to I−; [2] The solvent is changed from acetone to CH3CH2OH; [3] The alkyl halide is changed from CH3(CH2)4Br to CH3CH2CH2CH(Br)CH3; [4] The concentration of −CN is increased by a factor of five; and [5] The concentrations of both the alkyl halide and −CN are increased by a factor of five

Select the correct arrow-pushing mechanism for the formation of the more stable carbocation intermediate in he addition of a hydrogen halide to the following alkene. H-Br: O H-Br: + Br H-Br: H + :Br H-Br: Br

Does a rotation about the carbon-carbon sigma bond always happen in a E1 reaction? If not, why is it happening in this reaction?

The Wolff–Kishner reaction uses hydrazine (H2NNH2) and hydroxide (–OH) to reduce a carbonyl to the alkane. The first steps of the mechanism convert a carbonyl to a hydrazone in a manner similar to imine formation. Draw the mechanism arrows for the reaction from the hydrazone to the alkane. Be sure to add lone pairs of electrons and nonzero formal charges to all species.

ol The conjugate addition of an alkyl group to an a,ß-unsaturated ketone is one of the more useful 1,4-addition reactions, just as direct addition of a Grignard reagent is one of the more useful 1,2-addition reactions. Conjugate addition occurs via the use of a lithium dialkylcopper reagent, also called a Gilman reagent. The mechanism is thought to involve the addition of the dialkylcopper anion to the B- carbon to give a copper-containing intermediate. Transfer of an alkyl group to carbon and release of a neutral alkylcopper species completes the reaction. Draw curved arrows to show the movement of electrons in this step of the mechanism.
