Answer:
trans-4-tert-butyl-1-phenylcyclohexanol
Explanation:
The bulky tert-butyl group will occupy the equatorial position in the cyclohexanone ring.
It will hinder approach of the Grignard reagent from the bottom side of the molecule.
The reagent will attack from the top, so the product alcohol will be
<em>trans</em>-4-<em>tert</em>-butyl-1-phenylcyclohexanol.
Answer: 
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number
of particles.
To calculate the number of moles, we use the equation:

1 mole of zinc weighs = 65.38 g
moles of Zinc weigh = 
Thus mass of one atom of Zinc weigh 
Answer: 126.977g
Explanation: 4.1mol x 30.97g/1mol
