The number of hydrogens present in Loratadine, C 22 H ? ClN 2 O 2 , which has four rings and eight double bonds. Concept introduction: Each ring or a double bond in a molecule corresponds to a loss of two hydrogens from the formula of alkane . Hence two hydrogens are to be added for each to arrive at the molecular formula of the parent alkane. Further, if the molecular formula of a compound contains halogens, oxygen and/or nitrogen, then the number of halogens is to be subtracted from the number of hydrogens, the number of oxygens to be ignored and number of the nitrogens is to be added to the number of hydrogens, in arriving at the number of hydrogens. To determine: The number of hydrogens present in loratadine, C 22 H ? ClN 2 O 2 , which has four rings and eight double bonds.

Question

ох 4-tert-butyl oxy cyclohex-1-ene Incorrect, 1 attempt remaining The systematic name of this compound classifies the -OR group as a substituent of the hydrocarbon, which is considered the principal functional group. The ether substituent is named with the suffix 'oxy'. The general format for the systematic name of a hydrocarbon is: [prefix/substituent] + [parent] + [functional group suffix] Substituents are listed in alphabetical order. Molecules with a chiral center will indicate the absolute configuration at the beginning of its name with the R and S notation.

Chapter 7.SE, Problem 36AP

Interpretation Introduction

Interpretation:

The number of hydrogens present in Loratadine, C₂₂H_?ClN₂O₂, which has four rings and eight double bonds.

5. Compressibility (6 points total). The isothermal compressibility is a measure of how hard/easy it is to compress an object (how squishy is it?) at constant temperature. It is др defined as Br=-()=-(200²)T' (a) You might wonder why there is a negative sign in this formula. What does it mean when this quantity is positive and what does it mean when this quantity is negative? (b) Derive the formula for the isothermal compressibility of an ideal gas (it is very simple!) (c) Explain under what conditions for the ideal gas the compressibility is higher or lower, and why that makes sense.

19. (3 pts) in Chapter 7 we will see a reaction of halocyclohexanes that requires that the halogen occupy an axial position with this in mind, would you expect cis-1-bromo-3-methylcyclohexane or trans-1-bromo-3-methylcyclohexane to be more reactive in this reaction?
