A scientist has isolated a fatty acid that has 26 carbons. most of the carbon atoms in the fatty acid chain are connected by sin
Shtirlitz [24]
Answer:
            <span>Based on giveninformation, the compound is a <u>Poly Unsaturated</u> fatty acid.

Explanation:
                   Fatty acids are carboxylic acids with -COOH functional group and a chain of hydrocarbons.

Fatty Acids are classified as,

i) Saturated Fatty Acids:
                                      Those Fatty Acids in which there is no double bond between the carbon chain are called as saturated fatty acids. 

Examples:
                 Lauric Acid           </span>CH₃(CH₂)₁₀COOH<span>

                 Myristic Acid         </span>CH₃(CH₂)₁₂COOH<span>

                 Palmitic Acid         </span>CH₃(CH₂)₁₄COOH

ii) Unsaturated Fatty Acids:
                                      Those Fatty Acids in which contain a single double bond (mono-unsaturated) or more than one double bond (poly-unsaturated) d between the carbon atoms in a chain are called as unsaturated fatty acids. 

Examples:
                 <span>Linoleic acid
</span>
                 <span>Vaccenic acid

                 </span><span>Palmitoleic acid

The saturated fatty acid containing 26 carbon atoms is called as Cerotic acid. While cerotic acid containing a double bond at position 3 and 9 has a IUPAC name H</span>exacosa-3,9-dienoic acid with following structure.

Which step ONLY occurs in the formation of coal?
quester [9]

"Decaying swamps are covered with seawater" step ONLY occurs in the formation of coal.

<u>Option:</u> B

<u>Explanation:</u>

Coal production continues in regions of swampy wetlands because groundwater is near to or just above the topsoil. Because of this, organic matter is created quickly by the flora present-faster even than it can be broken down. Layers of organic matter are deposited in these areas, and then buried.

Based on the plants and circumstances present, the mechanism that produces coal varies somewhat in various areas but the ultimate method is similar. Coal production has two primary phases: peatification, and coalification. It is a solid black, readily combustible fossil fuel containing a large quantity of carbon-based material-about 50 percent of its mass.
