Explanation

Whey, the liquid part of milk after curdling, contains lactose, proteins, and nutrients that can be used by both:

- Bacteria – for fermentation (e.g., in yogurt or cheese production)

- Yeast – as a nutrient source in certain fermentation processes

Explanation

- Given: n = 4, l = 3

- When l = 3, it's an f-subshell

- The number of orientations = number of magnetic quantum number (mₗ) values = 2l + 1

- So, 2(3) + 1 = 7

Explanation

Bond order = ½ (Number of bonding electrons − Number of antibonding electrons)  

For H₂:  

- Bonding electrons = 2  

- Antibonding electrons = 0  

Bond order = ½ (2 − 0) = 1

Explanation

 Cleavage is the tendency of a crystal to break along specific planes of weakness.

Copper, being a metal, has a unique atomic structure that doesn't exhibit distinct planes of weakness.

When stressed, it tends to deform rather than cleave, resulting in a jagged fracture. 

Explanation

CH₃MgBr is a Grignard reagent (a source of CH₃⁻ nucleophile).

CH₃O is shorthand for methanal (HCHO) or a methoxy group, depending on context.

Assuming the intended compound is an ester like methyl formate (HCOOCH₃), then:

CH₃MgBr reacts with an ester in two steps:

1. First addition forms a ketone.

2. The second addition gives a tertiary alcohol after hydrolysis.

So, the final product is a tertiary (3°) alcohol.

Explanation

According to Raoult's Law, the relative lowering of vapor pressure for a solution is equal to the mole fraction of the solute. 

Raoult's Law states that the vapor pressure of a solvent in a solution is equal to the vapor pressure of the pure solvent multiplied by its mole fraction in the solution.

Therefore, the relative lowering of vapor pressure, which is the difference between the vapor pressure of the pure solvent and the vapor pressure of the solution, is directly proportional to the mole fraction of the solute. 

Explanation

 In fructose, the functional group ketone is present on carbon number 2.

This is why fructose is classified as a ketohexose, a six-carbon sugar containing a ketone group. 

Explanation

The coordination number of an ion in square planar geometry is:  4. 

A square planar geometry has the central ion bonded to four ligands, forming a square plane around

Explanation

Explanation

Ozonolysis cleaves the double bond in 3-Ethyl-2-pentene, forming two carbonyl compounds.

The double bond is between C2 and C3:

CH3–CH=CH–CH(CH2CH3)–CH3

On ozonolysis, it breaks at the double bond, yielding:

- Ethanal (CH3CHO) from the CH= part

- 3-Pentanone (CH3COCH2CH2CH3) from the rest
