Compounds X and Y are both C5H11Cl products formed in the radical chlorination of pentane. Base-promoted E2 elimination of X and Y gives, in each case, a single C5H10 alkene (ignoring double bond stereochemistry). Both X and Y react in SN2 fashion with sodium iodide in acetone; Y reacts faster than X. What is the structure of Y?

C5H11Cl with the Cl group attached to the chiral carbon

Explanation:

radical chlorination is given by:

C5H12 + Cl2 → C5H11Cl + HCl

Such reactions are unselective, the product  could either 1-chloropentanes, 2-chloropentanes, or 3-chloropentanes, all with the same molecular formula C5H11Cl but different structure(depending on on the carbon the chlorine is attached)

1-chloropentanes has its Cl group attached to a primary carbon

2-chloropentanes has its Cl group attached to a second carbon

3-chloropentanes  has its Cl group attached to a third  carbon

SN2 reactions occurs fastest on the primary carbon(chiral) which. Therefore Y is 1-chloropentane which has its Cl group attached to a primary carbon with no beta-branching will proceed the fastest.

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
