- Draw the structure(s) of all of the alkene isomers, C5H10, that contain a branched chain. Consider E/Z stereochemistry of alkenes.a) When (Z)-3-methylhex-3-ene undergoes hydroboration–oxidation, two isomeric products are formed. Give their structures, and label each asymmetric carbon atom as (R) or (S). What is the relationship between these isomers?Compound A and compound B are in equilibrium. Write a stepwise mechanism from compound Ato compound B showing ALL intermediates. Use curved arrows to symbolize the flow of electrons to show how each of the intermediates and products are formed. Show all lone pairs and formal charges. Lastly, explain which compound (Aor B) will be in higher concentration.
- Which will be more stable, cis or trans-1,4-tert-butylcyclohexane? Explain by drawing their structures?A compound C4H11N is known from its reactivity andspectroscopic properties to have no hydrogen atomsattached directly to the nitrogen atom. Write all structuralformulas consistent with this informationWhich of the statement is INCORRECT? a. The increase in stability of 2,4-hexadiene over 1,3-hexadiene is due to the increased double bond substitution of the former. b. The stabilization of dienes by conjugation is less pronounced than the aromatic stabilization of benzene. c. Resonance description in alkenes usually involves charge separation. d. Higher energy pi-orbitals often have decreasing number of nodes.
