Interpretation:
The detection of radiotracer needs to be explained.
Concept introduction:
A radiotracer is a radioisotope which emits radiations which are non-ionizing. It is used to detect the presence of an element.
Answer to Problem 75A
Radiotracer can be detected by placing body scanner and recording the
Explanation of Solution
Positron emission trans axial tomography (PET) is radiation-based medical diagnostic tool. In this procedure, a radiotracer which is decayed by positron emission is injected into the patient’s blood. Positrons emitted by the radiotracer cause gamma-ray emissions that are then detected by sensors surrounding the patient.
PET scans (positron emission tomography) are used for medical purposes like physiological activities like

- 2. Please consider the two all 'cis' isomers of trimethylcyclohexane drawn below. Draw the two chair conformers of each stereoisomer below (1 and 2) and calculate their torsional interaction energies in order to identify the lower energy conformer for each stereoisomer. Based on your calculations, state which of the two stereoisomers 1 and 2 is less stable and which is more stable. [1,3-diaxial CH3 CH3 = 3.7kcal/mol; 1,3-diaxial CH3 H = 0.88kcal/mol; cis-1,2 (axial:equatorial) CH3 CH3 = 0.88kcal/mol; trans-1,2-diequatorial CH3 CH3 = 0.88kcal/mol) all-cis-1,2,3- 1 all-cis-1,2,4- 2arrow_forwardNonearrow_forwardWhat is the mechanism by which the 1,4 product is created?

- Don't used hand raitingarrow_forwardIt is not unexpected that the methoxyl substituent on a cyclohexane ring prefers to adopt the equatorial conformation. OMe H A G₂ = +0.6 kcal/mol OMe What is unexpected is that the closely related 2-methoxytetrahydropyran prefers the axial conformation: H H OMe OMe A Gp=-0.6 kcal/mol Methoxy: CH3O group Please be specific and clearly write the reason why this is observed. This effect that provides stabilization of the axial OCH 3 group in this molecule is called the anomeric effect.
