Answer 1

Step-by-step explanation:

1 - Octyne is a member of the Alkyne family. Alkyne has a general formular is CnH2n-2 which is a homologous series with a least one carbon - carbon triple bond.

Where n is the number of carbon atoms needed in the structure.

The "1" prefix is an indicator for where the triple bond of the compound will be found which is at carbon -1. Because of its triple bond it is termed an unsaturated hydrocarbon. Their properties include:

1. Highly reactivity

2. Hydrophobic compound.

Octa- decribes the number of carbon atoms present in the compound which is 8. Also note that, it is not a cycloalkyne but a straight chain compound with a triple bond at one end.

So using the general formular, CnH2n-2

For n = 8,

1-Octyne is C8H14

Below in the attac is the structural formula of 1 - Octyne

Answer 2

Step-by-step explanation:

1-Octyne is a member of the Alkyne series, Alkyne is a homologous series with the general molecular formula;

CnH2n-2

n is a positive whole number which equal to or greater than 2.

i.e n= number of carbon given

In the case of the compound given (1-Octyne), the prefix “Oct” means 8, which is the number of

carbon atoms present in the compond while the suffix “yne” is

coined from the family name “Alkyne”

Therefore, C8H(2x 8) – 2 = C8H16-2 = C8H14

It is an unsaturated hydrocarbon, each alkyne molecule contains four hydrogen atoms

corresponding to alkane and two hydrogen atom less than the corresponding alkene. This is because

each alkyne molecule contains a carbon-carbon triple bond, where two carbon atoms are bonded

to each other by the sharing of three pairs of electrons.

The Alkyne family show a higher degree of unsaturation than the alkenes, hence they are chemically

reactive than alkane and alkene .
