Cyclopropane is a highly strained molecule. why? select all that apply.

Cyclopropane is a highly strained molecule because the conformations of the cycloalkanes are influenced by the torsional, angle strain, and steric strain. Cycloalkanes, which comprises more than three atoms of carbons are not flat molecules, they are puckered.  

The three and four-membered ring components exhibit angle strain and minimize the internal bond angles. The angle strain is generated when the bond angles deviate from the optimum tetrahedral angle, that is, 109.5 degree.  

Torsional strain is a resultant of eclipsing interactions, and steric strain is attained when the atoms are forced too close to each other.  

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion

hi i’m going crazy about going tomorrow and i’ll tell you what i’m doing and i wanna is a way ya
