Answer:

1,2-pentadiene < 1,4-pentadiene < cis-1,3-pentadiene < trans-1,3-pentadiene

Explanation:

1,3-pentadiene have two double bonds which are in conjugation, due to which delocalization occur. Delocalization of electrons more provide stability to 1,3-pentadiene as compared to 1,4-pentadiene and 1,2-pentadiene.

Among cis form and trans form of 1,3-pentadiene, trans form is more stable beacuse of less steric hindrance.

1,2-pentadiene is an example of cumulated diene. 1,4-pentadiene is an isolated diene. Cumulated dienes are less stable as two double bonds are present on the same carbon which leads to high electron density.

So, 1,2-pentadiene will be the least stable.

Order of dienes from least stable to most stable is as follows:

1,2-pentadiene < 1,4-pentadiene < cis-1,3-pentadiene < trans-1,3-pentadiene

Dafna11 [192]

Answer:

c and d are correct

Explanation:

In A, false because in Valence Electrons, the more the valences, the more stable an atom is.

In B, false because atoms cannot readily gain or lose valence electrons as the number of valence electrons is determined by the column they are in.

In C, true because the more the valence electrons, the more the stability of an atom.  

In D, true as electron placing is important and the reactivity of an atom is important.

So C and D are true!

Answer:

22.9 Liters CO(g) needed

Explanation:

2CO(g)     +   O₂(g)    =>    2CO₂(g)

? Liters          32.65g

                 = 32.65g/32g/mol

                 =   1.02 moles O₂

Rxn ratio for CO to O₂ = 2 mole CO(g) to 1 mole O₂(g)

∴moles CO(g) needed = 2 x 1.02 moles CO(g) = 2.04 moles CO(g)

Conditions of standard equation* is STP (0°C & 1atm) => 1 mole any gas occupies 22.4 Liters.

∴Volume of CO(g) = 1.02mole x 22.4Liters/mole = 22.9 Liters CO(g) needed

___________________

*Standard Equation => molecular rxn balanced to smallest whole number ratio coefficients is assumed to be at STP conditions (0°C & 1atm).
