Ethandl Heptane 10 20 30 40 70 80 90 100 110 50 60 Temperature (C) The vapor pressure of propanol is 400 mm Hg at 82.0 C. Why is trichloromethane more soluble than tetrachloromethane? Octane is non-polar organic compound. That eliminates hydrogen bonding and dipole-dipole interactions. What you have left is induced dipole to indu it is polar. WebThe presence of this substituent is likely to decrease the intermolecular interactions in the condensed phase rendering the evaporation of the neutral matrix molecules less energy demanding. c) CH3OH Hydrogen bonding CH3SH Dipole-dipole interaction Hydrogen bonding is the strongest intermolecular force, so CH3OH will have the higher boiling point. 0000003739 00000 n [tdc_zone type=tdc_content][vc_row][vc_column][td_block_trending_now limit=3][/vc_column][/vc_row][vc_row tdc_css=eyJhbGwiOnsiYm9yZGVyLXRvcC13aWR0aCI6IjEiLCJib3JkZXItY29sb3IiOiIjZTZlNmU2In19][vc_column width=2/3][td_block_slide sort=featured limit=3][td_block_2 border_top=no_border_top category_id= limit=6 td_ajax_filter_type=td_category_ids_filter ajax_pagination=next_prev sort=random_posts custom_title=SEA MOSS RECIPES][td_block_1 border_top=no_border_top category_id= sort=random_posts custom_title=SEA MOSS BEAUTY][td_block_ad_box spot_id=custom_ad_1][td_block_15 category_id= limit=8 sort=random_posts custom_title=SEA MOSS HEALTH BENEFITS][/vc_column][vc_column width=1/3][td_block_social_counter custom_title=STAY CONNECTED facebook=tagDiv twitter=tagdivofficial youtube=tagdiv border_top=no_border_top][td_block_9 custom_title=LIFESTYLE border_top=no_border_top category_id= ajax_pagination=next_prev sort=random_posts][td_block_ad_box spot_id=sidebar][td_block_2 sort=random_posts limit=3 category_id= custom_title=SEA MOSS BUSINESS][td_block_title][td_block_10 limit=3 custom_title= border_top=no_border_top tdc_css=eyJhbGwiOnsibWFyZ2luLXRvcCI6Ii0yMCJ9fQ==][/vc_column][/vc_row][/tdc_zone], Designed by Elegant Themes | Powered by WordPress.
