Explanation

 In the human body, ceruloplasmin acts as a carrier for the mineral copper.

The liver produces this protein and releases it into the bloodstream,

It transports about 95% of the copper found in the blood plasma. 

Explanation

Nuclear power plants generate electricity by using the heat released during nuclear fission—

The process where heavy atomic nuclei (like uranium-235) split into smaller nuclei, releasing a large amount of energy.

Explanation

Given:

Volume of compound C at STP = 0.112 dm³

1 mole gas at STP = 22.4 dm³

So, moles of C = 0.112 ÷ 22.4 = 0.005 mol

CO₂ produced:

Mass = 0.88 g

Moles of CO₂ = 0.88 ÷ 44 = 0.02 mol

Mole ratio:

0.005 mol of C → produced 0.02 mol of CO₂

Ratio CO₂ : C = 0.02 ÷ 0.005 = 4

👉 That means 4 carbon atoms are present in one molecule of C.

Explanation

In sp³d hybridization (trigonal bipyramidal geometry), the orbitals involved are one s, three p, and one dz² orbital.

This is because the dz² orbital has the correct symmetry along the z-axis to overlap effectively with s and p orbitals.

Explanation

NaCl is ionic; in aqueous solution it dissociates to give Cl⁻ ions.

It is immediately form a white precipitate of AgCl with AgNO₃.

Explanation

Xylene is a disubstituted benzene with two –CH₃ groups (electron donating, activating groups).

Both methyl groups are ortho/para directing, so the ortho-position becomes most electron-rich.

Hence, ortho-xylene sulphonates more easily than meta or para.

Explanation

1. Allyl bromide: CH₂=CH–CH₂Br
2. 1-Bromo-2-propene: CH₂=CBr–CH₃
3. 3-Bromo-1-propene: CHBr=CH–CH₃
4. Cyclopropyl bromide (Br–cyclopropane)
5. 1-Bromocyclopropane with double bond not possible (only stable cyclopropyl bromide).

Explanation

Electrophiles are electron-pair acceptors (electron-deficient species).

NH₃ is an electron-pair donor (Lewis base → nucleophile), not an electrophile.

Hg²⁺, BF₃, and AlCl₃ are electron-deficient and act as electrophiles.

Explanation

In calcium carbide (CaC₂), the carbide ion is C₂²⁻, where two carbon atoms are linked by a triple bond.

A triple bond consists of 1 sigma bond + 2 pi bonds between the two carbon atoms.

Explanation

Alkali metals have larger atomic size than alkaline earth metals, so their outer electrons are farther from the nucleus.

This makes it easier to remove an electron, giving them lower ionization energy than alkaline earth metals.
