A functional group . is where chemical reactions occur in an organic molecule. determines the family name of the compound. is a specific atom or group of atoms.

is where chemical reactions occur in an organic molecule

Explanation:

A functional group -

In the field of organic chemistry , the group of atoms which are responsible to show the specific chemical reaction of the molecule , is referred to as the functional group .

The functional group will always show same type of reaction for various range of compounds .

Hence , from the given question ,

The correct option is - is where chemical reactions occur in an organic molecule .

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
