Write the IUPAC name for the following compound: acetaldehyde

Acetaldehyde has a chemical formula CH 3 CHO . It has two carbons in its main chain and aldehyde as a functional group. The root word for two carbons is “eth-”, the primary suffix for the saturated compound is “-ane” and the secondary suffix for an aldehyde is “-al”. Hence, its IUPAC name is ethanal.

Write the IUPAC name for the following compound: acetylene

Acetylene has a chemical formula C 2 H 2 . It has two carbons in its main chain and a triple bond between the carbon atoms. The root word for two carbons is “eth-” and the primary suffix for unsaturated compound with triple bond is “-yne”. Hence, its IUPAC name is ethyne.

Name the following organic compound: The first homologue whose general formula is C n H 2 n .

The general name for the class of compounds having formula C n H 2 n is alkene. The first homologue whose general formula is C n H 2 n is ethene. It is an unsaturated compound having a double bond. It is produced mostly for industrial use.

Write the structural formula of the two isomers of butane.

Isomers are molecules that have the same molecular formula but different arrangements of atoms (or different structures). Two isomers are possible for butane C 4 H 10 . They are; butane and 2 - methylpropane. The structural formula for these isomers are as follows:

Give the IUPAC name for each of the following:

The IUPAC name of the given compound is but - 2 - ene or 2 - butene. There are four carbon atoms in the compound. Hence, the root word will be 'but' and a double bond is present at the second carbon atom. Hence, the suffix will be 'ene'.

Give the IUPAC name for each of the following:

The IUPAC name of the given compound is propanol. There are three carbon atoms in the compound, hence the alkane chain will be 'propane' and the functional group is alcohol, hence the suffix 'ol'.

Give the IUPAC name for each of the following:

The IUPAC name of the given compound is methanal. There is one carbon atom in the compound, hence the alkane chain will be 'methane' and the functional group is aldehyde, hence the suffix 'al'.

Give one phrase for the following statement: The tendency of an element to form chains of identical atoms.

The tendency of an element to form chains of identical atoms is called catenation. For example, Carbon has the unique ability to form bonds with other atoms of carbon, giving rise to large molecules. These compounds may have long chains of carbon, branched chains of carbon or even carbon atoms arranged in rings.
