The products formed during the reaction of carbon with conc. $H_2SO_4$ are:
$C + 2H_2SO_4 \longrightarrow \text{products}$

The most basic oxide of elements in group $14$ of the periodic table is

Which of the following organosilicon compounds on hydrolysis will give a three-dimensional silicone?

Which of the following elements does not form a monoxide?

In the following reaction,identify the nature of the product formed by the complete hydrolysis of the underlined atom at $R.T.$:
$\underline{Cr}O_2Cl_2 + 2H_2O \longrightarrow H_2CrO_4 + 2HCl$

Evaluate the following statements related to group $14$ elements for their correctness.
$(A)$ Covalent radius decreases down the group from $C$ to $Pb$ in a regular manner.
$(B)$ Electronegativity decreases from $C$ to $Pb$ down the group gradually.
$(C)$ Maximum covalence of $C$ is $4$ whereas other elements can expand their covalence due to presence of $d$ orbitals.
$(D)$ Heavier elements do not form $p\pi-p\pi$ bonds.
$(E)$ Carbon can exhibit negative oxidation states.
