Covalent compounds are compounds that are formed as a result of covalent bonding between nonmetal atoms.
Covalent compounds occur only between non metals, where atoms of the nonmetals involved join to form a covalent bond as a result of sharing of electrons.
Electrons shared during the formation of covalent bond, may be from one atom involved or each atom contributing equally to the bond formation.
An example of covalent compounds include, phosphorus (v) oxide, methane, water, CO2,etc.

Predict the two most likely mechanisms for the reaction of 1-iodohexane with potassium tert-butoxide.

Rudiy27

Answer:

C) SN2 and E2

Explanation:

For this question, we have analyzed the substrate and the base/nucleophile. The substrate, in this case, is 1-iodohexane and the base/nucleophile is potassium tert-butoxide.

Substrate

In the 1-iodohexane the iodide "I" is bonded to a primary carbon (carbon 1). Therefore we will have a primary substrate. If we have a primary substrate an Sn1 can not take place. We can not have a primary carbocation due to this instability. So, we can disccard options A) and B).

Base/nucleophile

In the potassium tert-butoxide we have an ionic compound. A positive charge is placed in the potassium atom a negative charge is placed in the oxygen of the ter-butoxide ion. So, we will have a strong base (a molecule with the ability to remove electrons) and a strong nucleophile (a molecule with ability to bond with an electrophile). With all this in mind, we can not have an E1 reaction.

With both analyses, the answer is C).

See figure 1

I hope it helps!
