Complete question along with options is attached below,
Answer: Option-B (Ethene) is the correct answer.
Explanation: In given options except option-B (an alkene) all options are example of alkanes.
Reason for reactivity of Alkene:
Alkenes are more reactive than alkanes because it consists of a pi bond. Thus, the electron density in this pi bond lies below or above the bond axis, hence making it more exposed and accessible for incoming electrophile.
Secondly, the
pi bond is weaker than sigma bond and can easily break down. This weakness originates due to less effective overlap of the orbitals forming pi bond as compared to the overlap resulting in the formation of sigma bond.
Therefore, alkenes can add Br₂ through a
electrophillic addition reaction, while alkanes fail to show such reaction.
Hexane is a type of hydrocarbon that consists of six carbon atoms surrounded by 14 hydrogen atoms
Answer:
0.07172 L = 7.172 mL.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.
</em>
where, P is the pressure of the gas in atm (P = 1.0 atm, Standard P).
V is the volume of the gas in L (V = ??? L).
n is the no. of moles of the gas in mol (n = 3.2 x 10⁻³ mol).
R is the general gas constant (R = 0.0821 L.atm/mol.K),
T is the temperature of the gas in K (T = 273 K, Standard T).
<em>∴ V = nRT/P =</em> (3.2 x 10⁻³ mol)(0.0821 L.atm/mol.K)(273 K)/(1.0 atm) = <em>0.07172 L = 7.172 mL.</em>
This answer is true because it's t same amount
Answer:
Iodine molecules containing two atoms of iodine (I2) each are non-polar. That is because when iodine bonds with another iodine atom they attract electrons and share them equally. Thus neither water nor potassium permanganate dissolves in hexane.
