Current Question (ID: 17898)

Question:

$\text{The chemical that is an excellent ‘green’ solvent as well as a greenhouse gas is:}$

Options:

1. $\text{Methanol}$
2. $\text{CFCs}$
3. $\text{Carbon monoxide}$
4. $\text{Carbon Dioxide}$

Solution:

$\text{CO}_2 \text{ is an excellent green Solvent as well as greenhouse gas.}$ $\text{STEP 1: A greenhouse gas is defined as any gaseous compound that is capable of absorbing infrared radiation thereby trapping and holding heat in the atmosphere.}$ $\text{Green solvents are environmentally friendly solvents, or biosolvents, which are derived from the processing of agricultural crops.}$ $\text{STEP 2: Supercritical carbon dioxide can be used as a more environmentally friendly solvent for dry cleaning over traditional solvents such as hydrocarbons, including perchloroethylene.}$ $\text{The elimination of hazardous organic solvents and the search for useful non hazardous solvents is a prime goal of green chemistry. CO}_2 \text{ as a liquid or supercritical solvent meets many of the characteristics of an ideal green solvent.}$
