B) Ethane has the formula C2H6. In terms of electronic structure,

k0ka [10]

Answer:

There is one single covalent bond between two carbon atoms.

Explanation:

We know that sharing of electrons form covalent bonds.

If we look upon K,L,M ,N shells of the carbon and hydrogen atoms.

We found that Hydrogen is having only $1$ electron in K shell.

And Carbon on the other hand is having $2$ electrons in K shell and $4$ electrons in L shell.

So carbon have $4$ valence electrons,and it can share $4$ bonds with any relevant atom to complete its octet.

And Hydrogen requires $1$ electron to complete its doublet.

Alkane general formula $C_{n}H_{2n+2}$

For ethane $n=2$

$C_{2}H_{4+2}$ $=$ $C_{2}H_{6}$

$1$ Carbon atom is shared by $3$ Hydrogen.

The remaining one electron $(4-3)=1$ of carbon will be shared with another carbon atom.

An image of the sharing of electrons attached below,

Hence we have only $1$ covalent bond between the two.

Predict the aldol product when the following ketone undergoes self-condensation in the presence of NaOH. Do not show the dehydra

Anit [1.1K]

Answer:

β-hydroxyaldehyde (an aldol) namely 3-Hydroxy butanal.

Explanation:

When acetaldehyde is treated with dil.NaOH it undergoes self condensation as it contains alpha-hydrogen atom in its compound forming β-hydroxyaldehyde (an aldol) namely 3-Hydroxy butanal. This compound upon further heating will eliminate a molecule of water forming aldol condensation product namely Crotonaldehyde Or But-2-en-al. see the diagram attached.
