Draw 3-ethylhexanoic acid. draw the structure in line-bond form. s

Answer : The line-bond formula for 3-ethylhexanoic acid is shown below.

Explanation :

Structural formula or bond-line formula : In the structural formula, the bonding and type of bonds which holds the atoms in molecule together are shown.

In bond-line formula, the lines are used between the bonded atoms and the atoms are also shown.

The given compound is, 3-ethylhexanoic acid.

In this compound, the parent chain is 6 membered, a substituent ethyl is present at 3rd position of the parent chain and the carboxylic acid (-COOH) functional group is attached to it.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
