What factor influences the specific rate constant of a first-order reaction?
The specific rate constant of a first-order reaction is temperature-dependent, meaning that it changes with changes in temperature. This is in contrast to the concentration of reactants, products, or time, which do not directly affect the rate constant.

Which ion is a strong nucleophile in a polar aprotic solvent?
In polar aprotic solvents, the fluoride ion exhibits a strong nucleophilic character due to the solvent's ability to stabilize the ion's charge and reduce its solvation. This makes fluoride a highly reactive nucleophile, capable of participating in various chemical reactions.
The question is about the formula of Silver nitrate. Silver nitrate has the chemical formula AgNO3. Among the given options, AgNO3 is the correct answer as it represents Silver nitrate. AgNO, AgNO2, and AgNO4 are either incorrect forms of Silver nitrate or are unrelated chemical compounds.

Which chemical test would not be positive for acetaldehyde?
Acetaldehyde is an aldehyde and readily undergoes oxidation. Iodoform, Benedict's, and Tollen's tests are all based on this oxidizing property. The Lucas test, however, is used to differentiate between alcohols and is not relevant to aldehydes.
Ozonolysis of benzene is a chemical reaction where benzene is treated with ozone (O3). The primary product of this reaction is Glyoxal (CHOCHO), an aldehyde. The presence of both C=C bonds in benzene allows for the formation of two C=O bonds during ozonolysis, resulting in the production of Glyoxal.

Which particle has the capability to expel protons from paraffins?
In the context of removing protons from paraffins, the correct answer is Neutron. Neutrons, unlike Electrons and Positrons, are neutral particles and can displace protons during chemical reactions. The option 'None of above has such capability' refers to Electrons and Positrons, which are charged particles and cannot directly expel protons from paraffins.
