Which reaction mechanism (SN2, SN1, E2, or E1) is best accelerated by the following interaction of sodium iodide with DMSO as a solvent (or co-solvent)?

What is the role of the G-protein gustducin in the taste signaling pathway?

Electrons in orbital A flow into orbital B to make orbital C. What type of orbital is C?

A homolytic cleavage of a molecule of H2 leads to which of the following products?

The enthalpy for hydrogenation of different isomers of butene is shown in the following figure. Which statement below best interprets this figure.

According to the Hammond postulate, what structure does the transition state resemble?

Epigenetics describes heritable traits that are not linked to changes in DNA sequence, but to chemical reactions that regulate the transcription of the genes. A common event is methylation of lysine residues on histone proteins, which results in regulation of gene expression. Which reaction energy coordinate would be consistent for the mechanism for the exergonic SN2 reaction shown below?

What dihedral angle does an anti-coplanar transition state refer to?

Which of the following statements about atrial natriuretic peptide (ANP) is true?
