How many alcohols and ethers share the molecular formula c2h6o?

Answer is: there are two compounds with molecular formula C₂H₆O, one alcohol and one ethar.

Alcohol with molecular formula C₂H₆O is ethanol or ethyl alcohol (C₂H₅OH).

Ethanol is a volatile, flammable, colorless liquid with characteristic odor.

Ether with molecular formula C₂H₆O is dimethyl ether (CH₃OCH₃).

Dimethyl ether is a colorless gas.

Alcohol :CH₃-CH₂-OH (ethanol)

Ether: H₃C-O-CH₃  (dimethyl ether)

Explanation:

Alcohols are compounds containing the hydroxyl or the -OH functional group i.e. R-OH where R is an alkyl or aryl group

Ethers are compounds with a general structure, R-O-R' where R and R' are once again either alkyl or aryl groups.

The given compound has a molecular formula: C₂H₆O

Structure with 'alcohol' -OH functional group

CH₃-CH₂-OH ethanol

Structure with ether functionality:

H₃C-O-CH₃     dimethyl ether

how to make a simple air condition

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
