Answer:
Axial position
Explanation:
In the reduction of 4-tert-butylcyclohexanone with sodium borohydride, the major product has the tert-butyl group in the equatorial position and the alcohol in the axial position.
The reason for this is that, axial bonds are parallel to each other. If substituents are larger than hydrogen, they experience a greater steric crowding in axial compared to the equatorial position. Therefore, many substituted cyclohexane compounds prefer a conformation in which the larger substituents are in equatorial position.
Answer:
The fuel value of 1 gram of this carbohydrate in a nutritional calorie is 4.0 kcal/G.
Sodium chloride is made from one sodium atom and one chlorine atom:
Sodium has a charge of +1, or just +.
Chlorine has a charge of -1, or just -.
These balance out.
The potential energy of the ball is 8 J.
<h3>What is mechanical energy?</h3>
Mechanical energy is given as the energy possessed by an object to do work. It is given as the sum of the kinetic energy and potential energy.
Mechanical energy = Kinetic energy + Potential energy
The given ball has:
- Mechanical energy = 25 J
- Kinetic energy = 17 J
The potential energy is given as;
25 J = 17 J + Potential energy
Potential energy = 25 J - 17 J
Potential energy = 8 J
The potential energy of the ball is 8 J.

Answer:
3) ester
Explanation:
Esterification is the process in which alkanol and alkanoic acids reacts in the presence of a catalyst and heat. The product is usually an ester(alkanoate) and water.
For the reaction between ethanoic acid and 1-butanol, the product is butylethanoate and water as shown below:
CH₃COOH + C₄H₈OH → CH₃COOC₄H₈ + H₂O
