What atomic or hybrid orbitals make up the bond between c2 and o in acetaldehyde, ch3cho?

2 answers:

8 0

Acetaldehyde is an organic compound (a compound containing C atoms) composed of a carbonyl group. On the other hand, a carbonyl group is a functional group containing C = O. The hybrid orbitals of a compound determines the number pi and s orbitals in the electronic configuration. For a single bond, there are two s orbitals. For double bonds, on the other hand, the number of s orbital bond is 1 while the number of pi bonds is 2. For triple bonds, there are three pi bonds present in the cloud.

Thus for a c = O bond, the atomic orbital configuration is sp3 containing 1 s orbital and 2 pi bonds.

Answer:

In terms of central atom carbon:

three sp2 hybridized orbitals

one "2p" orbital.

one sp2 hybridized orbital and one "2p" orbital bonds with oxygen atom.

Explanation:

In acetaldehyde we have two carbons.

One carbon is simple alkyl carbon

The other carbon is carbonyl carbon

The carbonyl carbon is bonded to the alkyl carbon and hydrogen by sigma bonds (one with each) and to the oxygen atom by one sigma and one pi bond.Which means that there are three sigma bonds and one pi bond.

The hybridisation of carbonyl carbon is sp2.

The atomic orbitals involved are:

three "2p" orbitals

one "2s" orbital

Out of the three "2p" orbitals : two are involved in hybridization.

The third one is showing side ways overlapping with the "2p" orbital of oxygen atom.

Suppose that 0.48 g of water at 25∘C∘C condenses on the surface of a 55-gg block of aluminum that is initially at 25∘C∘C. If the

Answer : The final temperature of the metal block is, $25^oC$

Explanation :

$heat_{absorbed}=heat_{released}$

As we know that,

$Q=m\times c\times \Delta T=m\times c\times (T_{final}-T_{initial})$

$m_1\times c_1\times (T_{final}-T_1)=-[m_2\times c_2\times (T_{final}-T_2)]$ .................(1)

where,

q = heat absorbed or released

$m_1$ = mass of aluminum = 55 g

$m_2$ = mass of water = 0.48 g

$T_{final}$ = final temperature = ?

$T_1$ = temperature of aluminum = $25^oC$

$T_2$ = temperature of water = $25^oC$

$c_1$ = specific heat of aluminum = $0.900J/g^oC$

$c_2$ = specific heat of water= $4.184J/g^oC$

Now put all the given values in equation (1), we get

$55g\times 0.900J/g^oC\times (T_{final}-25)^oC=-[0.48g\times 4.184J/g^oC\times (T_{final}-25)^oC]$

$T_{final}=25^oC$

Thus, the final temperature of the metal block is, $25^oC$

Describe the formation of ions by electron loss or gain

Ronch [10]

Explanation:

Ions form when atoms gain or lose electrons. This is so that they form a full outer shell of electrons. When an atom gains electrons it becomes a negative ion, because electrons are negatively charged. For example, all halogens (group 7 or 17) form negative ions as they gain an electron forming a 1- charge. When an atom loses electrons it becomes a positive ion, as it is losing some negative charge from the electrons. This would be for example, alkali metals (group 1) which lose an electron to form a positive ion with a 1+ charge, (ALL metals form positive ions).
