front 1 cycloalkanes / alicyclic compounds are what? | back 1 Saturated cyclic hydrocarbons |
front 2 What's the formula for alkenes? | back 2 CnH2n+2 |
front 3 Cycloalkanes have what traits? | back 3 Non polar Non hydrogen bonding Fairly Inert Low in flexibility |
front 4 Cycloalkanes with more carbon chains have what? | back 4 Rotational freedom |
front 5 Stereoisomer | back 5 Atoms connected in the same order but differing in a three-dimensional orientation. |
front 6 Stereochemistry | back 6 The three-dimensional aspects of structure and reactivity. |
front 7 Cis (Z) | back 7 Function group on the same side of the plane |
front 8 Trans (E) | back 8 Function group both on opposite sides of the plane |
front 9 Angle strain | back 9 Strain due to the compression and expansion of the bond angle. |
front 10 What are the 4 different bond angles | back 10 Propane- 60 degree Butane- 90 degree Pentane- 108 Hexane- 120 |
front 11 Which is more stained cyclohexane or cyclopropane | back 11 Cyclopropane |
front 12 What's torsional strain? | back 12 Strain due to the eclipsing bonds between neighboring atoms |
front 13 What's steric strain? | back 13 Strain due to repulsive interaction when atoms get to close to eachother. |
front 14 Whose bonds can bend? | back 14 Cyclopropane |
front 15 How is maximum bonding achieved in a unstrained alkene? | back 15 When two atoms have their overlapping orbitals pointing towards each other |
front 16 What does cyclobutane have? | back 16 Cyclobutane has less angle strain than cyclopropane but has more torsional strain because of its larger number of ring hydrogens. |
front 17 Cyclopentane has what? | back 17 Large torsional strain |
front 18 What is a chair conformation? | back 18 A three dimensional shape of a hexane, with no strains |
front 19 Twist boat conformation has what? | back 19 Both torsional and steric strain, higher in energy than the chair conformation- less stable |
front 20 Substituent positions for the chair conformation are? | back 20 Axial- Parallel to the ring axis Equatorial- are in the rough plane of the ring, around the ring equator. |
front 21 What is the ring flip? | back 21 chair conformations interconvert and exchange axial and equatorial positions. |
front 22 What is 1,3-diaxial interactions? | back 22 The energy difference between axial and equatorial conformations is due to steric strain |
front 23 What's more stable? Gauche or anti Butane | back 23 Anti Butane |
front 24 What is a polycyclic molecule? | back 24 when two or more cycloalkane rings are fused together along a common bond |
