Draw the structures of all monobromo derivatives of pentane, c5h11br, which contain a 4-carbon chain.
SVETLANKA909090 [29]

Two or more compounds that have same molecular formula but differ in the arrangement of atoms in molecule and thus posses different properties are known as isomers.

The molecular formula of pentane is C_5H_1_2 substituting one hydrogen from pentane with bromine results in the formation of monobromo derivatives of pentane having molecular formula, C_5H_1_1Br.

The structure of monobromo derivatives of pentane that is 1-bromopentane, 2-bromopentane, and 3-bromopentane and having molecular formula, C_5H_1_1Br is shown in the image.

The other two arrangements of monobromo derivatives of pentane that is 2-bromo-2-methylbutane and 2-bromo-3-methylbutane is shown in the image.

There are different structures of monobromo derivatives of pentane having molecular formula, C_5H_1_1Br which contain a 4-carbon chain are 1- bromo-2-methylbutane and 1-bromo-3-methylbutane shown in the image.

Draw the mechanism of the slow step that occurs in both first-order substitution and first-order elimination reactions for (R)-3
BartSMP [9]

Answer:

see explaination

Explanation:

We are given the (R)-3-bromo-2,3-dimethylpentane and asking to draw the curved arrow which is the showing the mechanism for first-order substitution and first-order elimination reactions. We know the formation of carbocation is the rate determining step in the first-order substitution and first-order elimination reactions.

So in the (R)-3-bromo-2,3-dimethylpentane there is –Br gets removed and formed the tertiary carbocation which is more stable, so the curved arrows in Box 1 to depict the flow of electrons and intermediate in Box 2.

A certain liquid has a density of 0.70g/m. Find the mass of 6.4L o this liquid
neonofarm [45]

The mass of the liquid is 4.8 kg.

6.4 L = 6400 mL

Mass = 6400 mL × (0.70 g/1 mL) = 4500 g = 4.8 kg
