Organic Chemistry (Intro)

Question 1

Lewis acid

Answer 1

Electron pair acceptor (Electrophile)

Question 2

Lewis base

Answer 2

Electron pair donor (Nucleophile)

Question 3

Free radical

Answer 3

Highly reactive, electrically neutral atoms or groups of atoms with an unpaired electron

Question 4

Homolytic Fission

Answer 4

Covalent bond breaks such that the shared pair of electrons are split equally between the two bonded atoms (forms free radicals)

Question 5

Heterolytic Fission

Answer 5

Covalent bond breaks such that shared pair of electrons are split unequally between two bonded atoms. One atom takes both electrons to form an anion

Question 6

Constitutional Isomerism

Answer 6

Same molecular formula, different structural formula

Question 7

Stereoisomerism

Answer 7

Same molecular formula and structural formula, different spatial arrangement of atoms

Question 8

Enantiomerism

Answer 8

Molecule has no plane of symmetry, a chiral centre, and a non-superimposable mirror image
