Answer:Photochemical chlorination of 2,2,4-trimethylpentane gives four isomeric monochlorides. (a) Write structural formulas for these four isomers. (b) The two primary chlorides make up 65% of the monochloride fraction. Assuming that all the primary hydrogens in 2,2,4-trimethylpentane are equally reactive, estimate the percentage of each of the two primary chlorides in the product mixture.Only one of the chlorine atoms in the molecule, 3,4-dichloronitrobenzene, will undergo nucleophilic substitution.

- Photochemical chlorination of 2,2,4-trimethylpentane gives you four isomeric monochlorides A. Write the structural formular for these four isomers B. The two chlorides make up 65% of the monochlorides fraction. Asumming that all the primary hyrogens in 2,2,4-trimethylpentane are reactive, estimate the percentage of each of the two primary chlorides in the product mixtureUnder strongly acidic conditions, hexane is observed to undergo an isomerization process, during which it is converted into branched alkanes having the same molecular formula as hexane (C6H₁4). The rate at which each constitutional isomer is produced is related to the type of acid that is used in the reaction and the degree of mixing that occurs during the reaction (J. Chem. Soc., Perkins Trans. 2 1999, 12, 2715-2718). Step 1 Draw a bond-line structure of hexane. Draw Your Solution There are four branched isomers of hexane. Draw bond-line structures of all four of its isomers. Draw Your SolutionOrganic chemistry student Peter is tasked with synthesizing (R)-3-ethylpentan-2-ol.

Which of the following statements would be MOST correct regarding the optical rotation of his synthetic sample (Note: the specific rotation of (S)-3-ethylpentan-2-ol is +28.2°). O [x] of the sample will be +28.2° O [x] of the sample will be 0° O [x] of the sample will be between 0° and -28.2° O [a] of the sample will be -28.2° O [x] of the sample will be between 0° and +28.2°
