<u>Answer:</u>
is an inorganic compound.
<u>Solution:</u>
- Firstly, all the known definitions of organic compounds excludes Carbonic acid and it's salt from organic compounds except if 'C' is present in the cation.
- Secondly, Sodium is a metal which organic compounds cannot posses as a compound.
- Lastly, there is absence of C-H bond which is present in all the organic compounds.
Hence, we can conclude that is an inorganic compound though there is presence of Carbon atom in it.
The true answer of your question is :
OH : HYDROXYL GROUP
NH2 : AMINO GROUP
CH3 : METHYL GROUP ( but in rather broader terms, that functional group of formula CnH2n+1 where n is an integer is called ALKYL GROUP where by substituting n by 1,2,3... we obtain methyl for n = 1, ethyl for n = 2, and propyl for n = 3 )
COOH : CARBOXYL GROUP is the correct answer since carbonyl is characterized by the presence of functional group C=O in general the formula of the compound would be
R-C=O-R’ where R and R’ are alkyl groups like methyl for example. However the carboxyl group could be thought of as a summation of carbonyl + hydroxyl ( CO + OH ) resulting thus in COOH.
I hope you’ll understand everything, anyway if not i’m always here to help. ♥️
Cardiac muscle is found in only the heart because the heart is also called cardiac and said to have cardiac muscle.the answer is b. hope this helps :)
