Many hunting dogs enjoy standing nose-to-nose with a skunk while barking furiously, oblivious to the skunk spray directed toward them. One moderately effective way of lessening the amount of odor is to wash the dog in a bath containing dilute hydrogen peroxide, sodium bicarbonate, and some mild dish detergent. Use chemical reactions to describe how this mixture helps to remove the skunk spray from the dog. The two major components of skunk oil are 3-methylbutane-1-thiol and but-2-ene-1-thiol.

- In the second paragraph you should explain why 2-chloro-2-methylpropane reacts with water via the SN1 mechanism instead of the SN2 mechanism, and then write the steps in the mechanism for this reaction. Then write the balanced equation for the reaction between 2-methyl-2-chloropropane and water. One of the products of this reaction is HCl. The rate at which HCl is produced is equal to the rate at which 2-chloro-2-methylpropane is consumed. In this experiment, the HCI will be neutralized by incremental addition of a sodium hydroxide solution. Write the balanced equation for the reaction between NaOH and HCI.arrow_forwardH3C CH3 H3C NA C→XT Br Br₂ CH₂Cl₂ H3C Electrophilic addition of bromine, Br₂, to alkenes yields a 1,2-dibromoalkane. The reaction proceeds through a cyclic intermediate known as a bromonium ion. The reaction occurs in an anhydrous solvent such as CH₂Cl₂. CH3 Br In the second step of the reaction, bromide is the nucleophile and attacks at one of the carbons of the bromonium ion to yield the product. Due to steric clashes, the bromide ion always attacks the carbon from the opposite face of the bromonium ion so that a product with anti stereochemistry is formed.

- Compounds containing a phenol group may work as ANTIOXIDANTS to prevent free radical damage. This is accomplished when a free radical (or UV light) encounters a phenol group, turning the phenol group into a radical. However, contrary to typical radical behavior, the structure of the phenol radical can neutralize (or quench) the unpaired electron. Specifically, the phenol structure neutralizes (or quenches) the unpaired radical electron by doing the following: taking the electron and The correct name (or abbreviation) of an example compound (discussed in the lecture videos) containing a phenol group with antioxidant properties is:arrow_forwardWhat is a protecting group in a multi synthesis reaction in organic chemistry?arrow_forwardAn electron-deficient carbon atom reacts with a nucleophile, symbolized as: Nu−.
