 Here are two short synthesis problems.show all the steps, intermediates, and include all reagents, catalysts and solvents. 

### Organic Chemistry Synthesis Problem

**Objective:**

Starting with acetylene (ethyne) and an alkyl halide of your choice, propose a synthesis to make:

(a) Pentanal  
(b) Hexane

**Molecular Structure Provided:**

- **Pentanal**: The image depicts the molecular structure of pentanal. It shows a linear carbon chain consisting of five carbon atoms. The carbon chain includes a carbonyl group (C=O) at the end, indicating it is an aldehyde. The carbonyl carbon is bonded to a hydrogen atom (H), which is characteristic of aldehydes.

**Instructions:**

Utilize acetylene and select an appropriate alkyl halide to devise a synthesis pathway for both pentanal and hexane. Consider standard organic synthesis techniques such as carbon chain extension, functional group transformation, and appropriate reagents to achieve the desired products.
