Choose the correct mechanistic pathway for each of the following questions: A. an El process
B. an SN2 process
C. an E2 process
D. an SN1 process
a. Chlorination of a 1° alcohol using Thionyl Chloride
b. Alkene formation via POCl3 reaction with a 2º alcohol

Chlorination of a 1° alcohol using Thionyl Chloride - an SN2 process

Alkene formation via POCl3 reaction with a 2º alcohol - an El process

Explanation:

For a primary alcohol, the chlorination occurs by SN2 mechanism. Remember that the order of SN2 mechanism is methyl > primary > secondary > tertiary. This means that a primary alkyl halide will undergo nucleophillic  substitution by SN2 mechanism.

For a secondary alkyl halide, we normally expect that the mechanism will be E2. When we use POCl3 and pyridine, the alkyl halide passes through a carbocation intermediate which is characteristic of an E1 mechanism.

answer: h+ its less than oh

explanation:

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
