Answer:

The Moon has an atmosphere.

Explanation:

The Moon has an atmosphere, but it is very tenuous. Gases in the lunar atmosphere are easily lost to space. Because of the Moon's low gravity, light atoms such as helium receive enough energy from solar heating so that they escape in just a few hours.

For alkyl halides used in SN1 and SN2 mechanisms, rank the leaving groups in order of reaction rate. You are currently in a rank

Alex777 [14]

Answer:

Iodide> Bromide > chloride > flouride

Explanation:

During a nucleophilic substitution reaction, a nucleophilie replaces another in a molecule.

This process may occur via an ionic mechanism (SN1) or via a concerted mechanism (SN2).

In either case, the ease of departure of the leaving group is determined by the nature of the C-X bond. The stronger the C-X bond, the worse the leaving group will be in nucleophilic substitution. The order of strength of C-X bond is F>Cl>Br>I.

Hence, iodine displays the weakest C-X bond strength and it is thus, a very good leaving group in nucleophillic substitution while fluorine displays a very high C-X bond strength hence it is a bad leaving group in nucleophilic substitution.

Therefore, the ease of the use of halide ions as leaving groups follows the trend; Iodide> Bromide > chloride > flouride

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:
Based on giveninformation, the compound is a Poly Unsaturated 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 CH₃(CH₂)₁₀COOH

Myristic Acid CH₃(CH₂)₁₂COOH

Palmitic Acid 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:
Linoleic acid

Vaccenic acid

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 Hexacosa-3,9-dienoic acid with following structure.
