Compare some of properties of butane; butene and butyne.(hint:nature of flame and coloure of Br2 inCCl4). ​

Consider the story you just read. all but one of the choices below indicate that something is living.

Which statement best describes the he properties of iconic compounds ?

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.
