Why can't 1−methylcyclohexanol be prepared from a carbonyl compound by reduction? select the single best answer?
forsale [732]
1−methylcyclohexanol is a tertiary alcohol. Tertiary Alcohols are synthesized by either reacting Ketone with Organometallic compounds like Grignard reagent or by hydration of substituted alkenes. <span>1−methylcyclohexanol can not be synthesized by reduction of carbonyl compound because it is not possible to have a starting carbonyl compound having carbonyl group along with three other alkyl groups (as carbon can only form 4 bonds).

Result:
           Tertiary alcohols don't contain a hydrogen atom at carbon attached to hydroxyl group that is why it is not possible to synthesize </span><span>1−methylcyclohexanol by reduction of carbonyl compound.</span>

A bowl containing 150 grams of water, is heated from 25 °C to 100 °C. The specific heat of water is 4.184 J/g°C. How much heat e
lyudmila [28]

Answer:

4.7 × 10⁴ J

Explanation:

Step 1: Given data

  • Mass of water (m): 150 g
  • Initial temperature: 25 °C
  • Final temperature: 100 °C
  • Specific heat capacity of water (c): 4.184 J/g.°C

Step 2: Calculate the temperature change (ΔT)

ΔT = 100 °C - 25 °C = 75 °C

Step 3: Calculate the heat required (Q) to raise the temperature of the water

We will use the following expression.

Q = c × m × ΔT

Q = 4.184 J/g.°C × 150 g × 75 °C = 4.7 × 10⁴ J

Balance the combustion reaction between propane and oxygen. If a coefficient of "1" is required, choose "blank" for that box.
alex41 [277]

The combustion reaction between propane and oxygen is C3H8 + 5O2 → 3CO2 + 4H2O. The key in the balancing of chemical reaction is to make sure that you got the exact chemical formula of the substance that is reacting and the yielded product. After getting the formula, identify first the hardest element/atom to be balanced such as Na, Zn, Cl, etc. Then proceed to the easier ones such as O, H. Make sure to not the atoms present in the molecule of the substance.
