Classify these structures as hemiacetal, acetal, or other.

Explanation:

Hello!

Let's solve this!

A hemiacetal is the product of a reaction between an aldehyde and an alcohol.

The structure is

      R

       |

RO-C-H

       |

      OH

An acetal has two alkoxy groups. The structure is :

        H

         |

 OH-C-OR '

         |

        OR ''

Of the compounds given, the first two are hemiacetals.

The next three are acetals and the last two are others.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

they are both synthetic elements
