Draw open chain structure of an aldopentose and aldohexose. Predict the number of asymmetric carbon atoms present in each.

Explanation

To solve the question, we will follow these steps:

### Step 1: Draw the open chain structure of an aldopentose.
An aldopentose is a monosaccharide that contains five carbon atoms and an aldehyde group. The general structure can be represented as follows:

1. Start with the aldehyde group (CHO) at one end.
2. Attach four carbon atoms in a straight chain.
3. Add hydroxyl groups (OH) to the carbon atoms, ensuring that the last carbon (C5) has a CH2OH group.
