Which of the following statements concerning commonly encountered alcohols is incorrect?
- a. Wood alcohol and methyl alcohol are two names for the same compound.
- b. Denatured alcohol is drinking alcohol rendered unfit to drink.
- c. Rubbing alcohol is a 70% aqueous solution of ethyl alcohol.
- d. no correct response
Interpretation:
The statements that is incorrect concerning the commonly encountered alcohols has to be identified.
Concept Introduction:
Alcohols are commonly encountered in our day-to-day life. Some of the commonly encountered alcohols are, methanol, ethanol, propanol, ethylene glycol, propylene glycol, glycerol.
Reason for correct option:
A 70% isopropyl alcohol‑30% water solution is marketed as rubbing alcohol. Isopropyl alcohol has rapid evaporation rate and this creates a great cooling effect when applied on the skin.
In the given options, option (c) tells that rubbing alcohol is a 70% aqueous solution of ethyl alcohol. This is an incorrect one because rubbing alcohol is a 70% aqueous solution of isopropanol.
Hence, the correct option is option (c)...
