Question: USS Atlanta ( 1861 ) Atlanta was a casemate ironclad that served in the Confederate and Union Navies during the American Civil War . She was converted from a Scottish @-@ built blockade runner named Fingal by the Confederacy after she made one run to Savannah , Georgia . After several failed attempts to attack Union blockaders , the ship was captured by two Union monitors in 1863 when she ran aground . Atlanta was floated off , repaired , and rearmed , serving in the Union Navy for the rest of the war . She spent most of her time deployed on the James River supporting Union forces there . The ship was decommissioned in 1865 and placed in reserve . Several years after the end of the war , Atlanta was sold to Haiti , but was lost at sea in December 1869 on her delivery voyage . fill in the blank : USS Atlanta ( 1861 ) Atlanta was a casemate ironclad that served in the Confederate and Union Navies during the __________________ Civil War .

Answer: American

Question: In 1994 , two years after Fey joined Chicago 's Second City improvisational theatre troupe , she began dating Jeff Richmond , a piano player who later became Second City 's musical director and then a composer on 30 Rock . They married in a Greek Orthodox ceremony on June 3 , 2001 . They have two daughters : Alice Zenobia Richmond ( born September 10 , 2005 ) and Penelope Athena Richmond ( born August 10 , 2011 ) . In April 2009 , Fey and Richmond purchased a US $ 3 @.@ 4 million apartment on the Upper West Side in New York City . Fey has a scar a few inches long on the left side of her chin and cheek , the cause of which remained unexplained to the public until a 2008 Vanity Fair profile by Maureen Dowd , and subsequently in her autobiographical book , where she revealed that during the spring semester of kindergarten , I was slashed in the face by a stranger in the alley behind my house. fill in the blank : In 1994 , two years after Fey joined Chicago 's Second City improvisational theatre troupe , she began dating Jeff Richmond , a piano player who later became Second City 's musical director and then a composer on __________________ Rock .

Answer: 30

Question: The reaction mechanism for the Johnson Corey Chaykovsky reaction consists of nucleophilic addition of the ylide to the carbonyl or imine group . A negative charge is transferred to the heteroatom and because the sulfonium cation is a good leaving group it gets expelled forming the ring . In the related Wittig reaction , the formation of the much stronger phosphorus @-@ oxygen double bond prevents oxirane formation and instead , olefination takes place through a 4 @-@ membered cyclic intermediate . The trans diastereoselectivity observed results from the reversibility of the initial addition , allowing equilibration to the favored anti betaine over the syn betaine . Initial addition of the ylide results in a betaine with adjacent charges ; density functional theory calculations have shown that the rate @-@ limiting step is rotation of the central bond into the conformer necessary for backside attack on the sulfonium . The degree of reversibility in the initial step ( and therefore the diastereoselectivity ) depends on four factors , with greater reversibility corresponding to higher selectivity : Stability of the substrate with higher stability leading to greater reversibility by favoring the starting material over the betaine . Stability of the ylide with higher stability similarly leading to greater reversibility . Steric hindrance in the betaine with greater hindrance leading to greater reversibility by disfavoring formation of the intermediate and slowing the rate @-@ limiting rotation of the central bond . Solvation of charges in the betaine by counterions such as lithium with greater solvation allowing more facile rotation in the betaine intermediate , lowering the amount of reversibility . fill in the blank : The reaction mechanism for the Johnson Corey Chaykovsky reaction consists of nucleophilic addition of the ylide to the carbonyl or __________________ group .

imine
