As the piece of metal skitters across the surface of the water in a beaker and — particularly in the case of potassium — it appears to catch fire, it is not obvious that the explanation for both phenomena lies in the production of hydrogen gas.

Why does the dehydration of an alcohol more often use concentrated sulfuric acid, H 2 S O 4 HX2SOX4, as the acid catalyst rather

Dimas [21]

KAnswer:

See explanation

Explanation:

It is more common to use H2SO4 for dehydration reaction rather than HCl because HCl contains a good nucleophile,the chloride ion.

Owing to the presence of the chloride ion, a substitution reaction involving the chloride ion may also proceed also thereby affecting the elimination reaction.

Also, concentrated H2SO4 is a very good drying agent thus, as long as it is used, the alcohol substrate is completely dehydrated to yield the alkene.

Note that HCl is not a dehydrating agent.

onsider the structure. a carbon is bonded to two three carbon chains and a branched alkane. the branched alkane is a 2 carbon ch

pshichka [43]

If we consider a structure in which a carbon is bonded to two three carbon chains and a branched alkane then the branched alkane is a 2 carbon chain with a ethyl on Carbon 1 then the correct name of the structure is <u>4-(isopropyl)heptane. </u>

The two three carbon chains bonded to the carbon atom will form the parent chain of this structure and this chain will have 7 carbon atoms in it.

Since this chain is that of an alkane and it has no functional group attached so the root name will be heptane.

Now, we have to add a prefix by naming the branched alkyl chain. The branched chain has 3 carbon atoms in it with a methyl group on carbon 1.

So, this name of this group will be propyl.

The position of this propyl group is 4th on the parent chain so the full name of the structure will be 4-(isopropyl)heptane.
