Question

The multiple covalent bond in a molecule of 1-butene is a

(1) double covalent bond that has 6 shared electrons
(2) double covalent bond that has 4 shared electrons
(3) triple covalent bond that has 6 shared electrons
(4) triple covalent bond that has 4 shared electrons

Answer 1

(2) double covalent bond that has 4 shared electrons

Answer 2

Answer: Option (2) is the correct answer.

Step-by-step explanation:

An alkene is a molecule that contains a hydrocarbon chain with atleast one double bond.

For example,
`H_(2)C=CH-CH_(2)-CH_(3)` is a 1-butene molecule and it contains one double bond that consists of four shared electrons.

On the other hand, a molecule of hydrocabon that contains a triple bond is known as an alkyne. Whereas a hydrocarbon that contains only single bonds is known as an alkane.

Thus, we can conclude that the multiple covalent bond in a molecule of 1-butene is a double covalent bond that has 4 shared electrons.
