What are the names of the given molecules? #a.#

And #b.#

Answer 1

#(a)# is a hexane derivative. #(b)# is a nonane derivative

The longest hydrocarbyl chain must be found in each of these problems. When we write out the formula, we attempt to assume the highest possible degree of symmetry for clarity's sake.

The longest chain in #(a)# is six carbons long, i.e. a #"dimethylhexane"#. I leave you to find it, and I leave you to name it. The longest chain in #(b)# is 9 carbons long, a substituted #"nonane"#, with ethyl and methyl substituents along the chain.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
