Answer:
I wish I spoke this languge.
Explanation:
The answer is (2). To calculate the density, you need to divide the mass with volume. When doing division, the significant figures of result is the minimal of the numbers using before. So the answer is 2.
Answer:
because the load arm is greater than the effort arm. As we know that when the load arm is greater than the effort arm, the mechanical advantage will always be lesser than one, which results in gain in speed
The reaction of 2-methylcyclohexanone with CH3MgBr followed by neutralization gives two alcohols. These two alcohols are cyclohexanol and ethanol. This reaction involves Grignard reaction.
<h3>
What is Grignard reaction?</h3>
- Alkyl, allyl, vinyl, or aryl-magnesium halides (the Grignard reagent) are added to a carbonyl group in an aldehyde or ketone to produce the Grignard reaction. The creation of carbon-carbon bonds depends on this process.
- An organic halide reacts with magnesium, but it does not undergo a Grignard reaction; instead, it produces a Grignard reagent.
- The carbon bonded to magnesium acts as a nucleophile and targets the electrophilic carbon atom that is present within the polar bond of a carbonyl group because carbon is more electronegative than magnesium.
- Usually, the Grignard reagent is added to the carbonyl through a six-membered ring transition state.
