Deduce the structure of an unknown compound using the data below. Molecular formula: C4H8O IR: 1717 cm-1, no IR absorptions above 3100 cm-1. NMR δ 0.95 (3H, t, J = 8 Hz), δ 2.03 (3H, s); δ 2.38 (2H, q, J = 8 Hz) ppm

Forgot the question hahaha

Sorry i dont understand the question can you rephase it?

3is your answer to yuor question

Large asteroid and comet impacts. because they can have a huge impact on the environment, such as a loss of land, and crust on the earth with the big holes they produce. on the other hand, volcanic eruptions can also cause change within the environment by producing land, but im actually not quite sure which one would be a better answer, hopefully you read this and didnt just flat out choose the first sentence i have spoken! your welcome~
