How is an alkyl halide extended by ONE carbon?

Answer 1

We could (i) pour the Grignard reagent onto dry ice, or (ii) treat iodomethane with cyanide and hydrolyze. In each case we extend the carbon chain by 1.

There are numerous options:

#H_3C-I + Mg rarr H_3C-MgI + CO_2 rarr H_3C-CO_2^(-)(MgI)^+#

#H_3C-I + N-=C^(-) rarr H_3C-C-=N + I^(-) rarr "acid hydrolysis" rarr H_3C-CO_2H#

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.
