Provide a structure for the following compound: ei mass spectrum: two molecular ions of about equal intensity at m/z = 180 and 182; ir: 1740 cm–1; a. δ 1.30 (3h, t j = 7 hz); b. δ 1.80 (3h, d, j = 7 hz); c. δ 4.23 (2h, q, j = 7 hz); d. δ 4.37 (1h, q, j = 7 hz).

i think that the answer is c

gas

explanation:

smoke is the matter of a gas

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
