keep receiving a 4/5 points.
Which of the following statements regarding acetals is true? Select all correct answers. Acetals can be formed from aldehydes or ketones plus water. Acetals are stable to base, but will react with acids. Acetals are formed under equilibrium conditions, so excess alcohol is often employed. Acetals can be used as temporary protecting groups for aldehydes and ketones. Acetals will react with most nucleophiles. Acetals will react with most reducing agents. An acetal will contain...

2. Which of the following statements is true of cyclic forms of 6-carbon sugars? a. Conversion of the linear form to the cyclic form results from a reaction between the 0 3 carbonyl C and an alcohol in the same molecule. b. Six-C sugars only form 6-membered rings c. The cyclic form has the same number of chiral centers as the linear form. d.xAt room temperature in aqueous solutions, glucose is primarily in the linear form Both a and b...
