B.
Pretty much common sense.

When 1-iodo-1-methylcyclohexane is treated with NaOCH2CH3 as the base, the more highly substituted alkene product predominates. When KOC(CH3)3 is used as the base, the less highly substituted alkene predominates. Give the structures of the two products and offer an explanation.

Answers

Answer:

See explanation

Explanation:

In this case, we have 2 types of reactions. CH_3CH_2ONa is a strong base but only has 2 carbons therefore we will have less steric hindrance in this base. So,  the base can remove hydrogens that are bonded on carbons 1 or 6, therefore, we will have a more substituted alkene (1-methylcyclohex-1-ene).

For the  KOC(CH_3)_3 we have more steric hindrance. So, we can remove only the hydrogens from carbon 7 and we will produce a less substituted alkene (methylenecyclohexane).

See figure 1

Theoretical yield
2.05 g salicylic acid x (180g aspirin/1 mol) x (1 mol/138 g salicylic acid)

Answers

The question is incomplete; part of the data required in the question are shown:

Theoretical Yield: 2.05 g salicylic acid x (180g aspirin/1 mol) x (1 mol/138 g salicylic acid) 2. Mass of filter paper 2.56 g 3. Mass of filter paper and aspirin 5.42 g 4. Mass of aspirin (3-2) g. Percent Yield [(4)/(1)] x 100

Answer:

107%

Explanation:

We can calculate the theoretical yield as shown;

2.05g salicylic acid × 180g aspirin/1mol × 1 mol/138g of salicylic acid

Theoretical yield= 2.67 g of aspirin

Actual yield of aspirin is obtained from the experimental data;

Mass aspirin + filter paper= 5.42 g

Mass of filter paper= 2.56 g

Mass of aspirin= 5.42 g -2.56 g = 2.86 g

Hence actual yield of aspirin = 2.86 g

Percentage yield = actual yield/theoretical yield × 100

Percentage yield = 2.86/2.67 ×100 = 107%

Answers

Water is in the solid phase at 0.25 atm and 0°C.

In what phase is water at 25?

A pressure of 50 kPa and a temperature of 50 °C correspond to the “water” region—here, water exists only as a liquid. At 25 kPa and 200 °C, water exists only in the gaseous state.

What phase is water in at 0 C?

Under standard atmospheric conditions, water exists as a liquid. But if we lower the temperature below 0 degrees Celsius, or 32 degrees Fahrenheit, water changes its phase into a solid called ice.
