- Radical chlorination of pentane is a poor way to prepare 1-chloro pentane but radical chlorination of neopentane is a good way to prepare neopentyl chloride explainPhotochemical 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 mixture1,3-pentadiene reacts with HBr. When the double bond at the 3-position reacts, the hydrogen attaches to the 4-carbon, thus forming an allylic carbocation with delocalized electrons. This carbocation has another resonance structure. Because there are equal amounts of diene and hydrogen bromide, in which molecule only one of the double bonds reacts. Which of the following correctly describes this new resonance structure? a) It has a double bond between carbons 3 and 4 b) It has a positive charge on carbon 2 c) It has a positive charge on carbon 4 d) It has a double bond between carbons 2 and 3
