-1 -1 A compound with molecular mass 158 absorbs in the UV region at 225 nm. In IR spectrum, absorption bands are formed at 3077-2857 cm¹¹ (m), 1828 cm¹ (s), 1757 cm²¹ (m) and 1456 cm¯¹ (m). In NMR two signals are observed. 8 = 2.7 (septet, J = -1 = 6.7 Hz, 1 H), and 1.2 (d, J 6.7 Hz, 6 H). Predict the molecular structure of the unknown compound and justify your answer.
