the robinson annulation involves two sequential reactions, a michael addition and an aldol condensation, resulting in the formation of a cyclohexenone derivative. draw the structure of the two neutral reactants required to form the product shown.

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
